Launch HN: Yotta Savings (YC S20) – Behavioral psychology to help people save

240 points by adammoelis ↗ HN
Hey HN! We are Adam & Ben, co-founders of Yotta Savings (https://www.withyotta.com/), an app that uses behavioral psychology to help people save money by making saving exciting. We were inspired to build Yotta by the Premium Bond program (https://en.wikipedia.org/wiki/Premium_Bond) in the UK and a Freakonomics episode on prize-linked savings (https://freakonomics.com/podcast/say-no-no-lose-lottery-rebr...).

Premium Bonds is a government-run prize-linked savings program in the UK that started in 1956. It’s a savings account where people get chances to win monthly prizes through a random chance raffle. The more you save, the more entries you get. Premium Bonds are popular because many people prefer the chance to win a life-changing amount of money rather than a small interest payment from a bank. As a result, the program has been successful: over 23M people save through Premium Bonds (33% of the population) with over $100B deposited.

Human nature makes it difficult to adopt habits we know are healthy in the long-run but painful in the short run. The idea behind prize-linked savings is to use psychology to make saving exciting in the short run so that people will get the long run benefit. Even if you don’t win a prize, at least you still have access to your savings. You can’t lose anything other than the opportunity cost of interest at another bank.

In the U.S, people also like the chance to win a life-changing amount of money. This is what drives much of the $80 billion ($640 per household) spent on the lottery every year despite it being a hugely negative expected value proposition. Prize-linked savings was illegal in the U.S until 2015 when the American Savings Promotion Act was passed based on evidence showing prize-linked savings programs help people save more, especially in financially vulnerable populations.

We started building this 9 months ago. Ben and I are both former finance people turned tech people. As personal finance and behavioral psychology nerds (Nudge, Thinking Fast and Slow, etc.), we were excited by the idea of building a product that could help people, but that also had big business potential.

The market for consumer deposits in the U.S is huge. We make money by earning interest from our partner bank. We view our savings product as an entry point into the banking market, with the potential to offer a variety of revenue generating services to our users as other neo-banks have done. We plan to differentiate ourselves from other neo-banks by always offering products that make use of behavioral psychology to nudge people toward healthier financial habits.

With our app, you save money in an FDIC insured account. For every $25 you save, you get a recurring ticket into weekly random number drawings with chances to win prizes ranging from $0.10 to the $10 million jackpot. We provide a rate of return on savings that on average is in-line with the top yielding savings accounts out there like Marcus or Ally. You might get a higher return if you’re lucky and win more prizes than expected. You might get a lower return if you win fewer prizes than expected. Even in a worst case scenario where you never win a prize, you still have your savings.

Yotta is free. The $10 million jackpot would be paid out by our insurance partner. We are funding a jackpot via insurance to solve the chicken and egg problem of offering a life-changing jackpot that we hope will motivate people, even if the odds are extremely low that you’ll win it.

Hope you guys check it out. Happy to answer any questions, and looking forward to any feedback.

One of those brilliantly simple ideas, I'm already in for 10 tickets and have shared it with a bunch of friends.
Thanks and thanks for sharing it! Would love any feedback as you play with the app. adam@withyotta.com or here
Does this app only work in certain countries? Edit: great idea
You have to be a U.S resident in order to win prizes right now unfortunately, so basically yes
How do you check eligibility?
We don't verify for the smaller prizes. For bigger prizes, we verify after the fact and confirm with the winner.
How much does the insurance cost? Was it hard to find someone wiling to insure that?

Finally, you pay 0.2% but Ally pays 1% yet you say your rates are as good.

On the interest rate side, the 0.20% is the base rate. If you win no prizes, you get that. Prizes comprise the bulk of the value from Yotta. Your total return is prizes + the base rate.

On the insurance side, there are specialty insurance companies that do this kind of thing, similar to hole in one prizes or half court shot prizes at sporting events.

We pay them a mark-up on expected value. Since the risk they're taking is purely mathematical random chance, it's pretty much the best type of insurance for someone to underwrite. There is no uncertainty about what the risk is to them, unlike most other insurance where people are using actuaries to estimate what the risk is, but it's not actually known for sure.

Why bother insuring yourselves then? Just to cover yourselves incase you get "unlucky"?

Couldn't you structure the contest so that you know you'd payout $X per week and not need insurance?

I guess people eventually could win twice in a short span if they're unlucky and they'd be out of money
Even if somebody won the jackpot only once, I assume they'd be out of money by far, which is why insurance is needed.
The 0.2% is the base (minimum) rate, not the average rate.
> We provide a rate of return on savings that on average is in-line with the top yielding savings accounts out there like Marcus or Ally. You might get a higher return if you’re lucky and win more prizes than expected. You might get a lower return if you win fewer prizes than expected. Even in a worst case scenario where you never win a prize, you still have your savings.

Can you elaborate more on this? (Maybe you can't because of the SEC?) APY of Ally is 1.0% right now, vs. 0.20%, so are the expected value of winnings 0.8%?

APY in most savings account changes quarterly so doing temporal comparisons does not have much bearing here.
Yeah fair point. Our all-in rate (base rate + prizes) will move with market cycles as well to match HYSAs
Yeah. Right now, the EV from prizes is actually higher than that. We are subsidizing to provide an even better value for early users. But in the long run, that's exactly right. The base rate plus prizes will be, on average, what you would earn in a vanilla but high yielding HYSA
And can/will you disclose the difference? :D
We can and may do this sometime soon. The official rules has the prizes and odds laid out, so you could back into it with some math.
Did some quick excel sketching here: https://docs.google.com/spreadsheets/d/17t00LzdgRcC8dtVKnTwK...

Odds from here: https://www.withyotta.com/official-rules

I might be completely wrong but looks like your estimate yield is heavily dependent of amount of other people saving as well.

I bet the real model gets pretty damn interesting. Would love to get a closer look for sure.

If you wanted to be a bit more "evil genius". It would be interesting if somehow the money in the grandprize grew based on how many people participated. This would give people incentive to join and lower the overall EV for everyone, but also give you guys more funds to manage :)

A few errors in the spreadsheet:

- Odds for the $0.20, $0.80 prizes are slightly off.

- The $15 and below prizes are not split between participants, so one would not need to consider the number of other entries for winning those prizes.

If one just considers the $15 and below prizes, I think the odds work out to about 3.2% per year, making it about a 3.4% expected interest total.

(comment deleted)
Really interesting concept! Are you planning on adding index fund investing in the future? It seems like you could incentivize investors to take a long term view with a similar, gamified approach.
We haven't thought about this yet but that's interesting. What kind of index fund gamification do you have in mind?
There was a company, forcerank, that was fantasy stock market. Rank stocks based on expected performance, and winner gets points, with cash prizes. They ran into a little SEC trouble, so careful with gamificating investing. https://www.sec.gov/news/pressrelease/2016-216.html

That said, it was a fun idea. Instead of picking lottery numbers, ranking tickers in the right order, and then pulling a date out of a hat? Something that only operates on past data?

Interesting I'd never seen this. We will look into this for sure. Thanks for sharing
Perhaps instead of paying out the dividend payment as usual, you can make the user receive tickets based on how many index fund shares they own, and you can fund a lottery using the dividend payments. The user can sell their index fund at anytime, so it would be the same as keeping their money in the savings account except they have better odds of beating inflation than a savings account.

If you limit the savings options to tried and trusted savings vehicles - savings account, total bond market, total US market and total international - perhaps you can instill investment knowledge in the users on top of the good savings practices.

The grand prize of $10,000,000 will be paid out as... $5,800,000? I don't understand how you justify saying (as far as I can tell) "The grand prize is $10,000,000. We reckon you could invest $5,800,000 and make $10,000,000 in 40 years, so we will give you $5,800,000 instead".
A fair point for sure. The rationale is the $10 million headline is the annuity value of the jackpot, and it's standard practice for sweepstakes or the PowerBall/MegaMillions contests to use the annuity value for promotion in marketing materials and on the website.
So if I buy into a 100m dollar powerball, I'm actually getting the net present value of 100m in 40 years? I'm amazed this is standard practice
Yeah exactly. Almost any grand prize you see is really the sum of the annuity value. We kind of have to use the same practice in order to be competitive, and we think a lot of people assume it's the annuity value sum as well. (https://www.magnifymoney.com/blog/banking/powerball-annuity/)
You should definitely rethink this. You're a savings account. Be honest (read: obvious and clear) with your customers.
It’s common knowledge that jackpots have an annuity or a lesser lump sum, that’s how lotteries work already. This is really just a way to gamify savings as a lottery, I think it’s a great idea and may sign up. I have a really low yield savings account right now anyway and was planning to sign up for an online high yield account.
Yes, but here you can't get the annuity. You can only the lesser lump sum, which after taxes won't be enough to get the annuity.
You're talking about lotteries. I'm talking about savings accounts. My point is that savings accounts should be held to a higher standard, because obviously.
But this product is literally a savings account with a lottery attached to it. Why would you not use the terminology/methods used by the lottery industry when describing the lottery aspects of the account?
If you do not understand, I cannot help you.
I think you could flip the status quo on its head, by promoting a full 10M (or 5M...), and making it clear it is NOT the annuity value sum like you do for lesser prizes, since I would argue that your competitivity/differentiation comes from the fact that you don't lose money to play.

Also describing the lottery mechanism without any gotcha is the right thing to do for consumers, and being in the unique position you are, you have the opportunity to lead that change.

With powerball I think you get the 100m spread out over 30 years or a lump sum now which is less.
There's that psychology "helping" us
The irony of using the promotional approach of an awful poverty tax by a startup focused on promoting saving.
It‘s pretty darn smart. A lot of people I know play the lottery instead of putting a couple of bucks to the side. Seems like a win-win
Somewhere I read an argument that numbers games (private, local lotteries, sometimes run by organized crime) helped some poor people by acting as a form of savings, except one that paid a negative interest rate and where you couldn't control the timing of when you got your savings out.

That sounds like a super-awful kind of savings account, but I think this argument assumed that many numbers-game players' next-most-preferred use of the money they would bet on it was even less like savings, so it could still be helpful by pulling money away from other things. Of course, that's a pretty big and pretty specific assumption.

This project and the idea that inspired it are a way better form of savings because the savers can actually access their principal and don't actually have to pay the bank.

This is straight up lie.
This is a very low-quality comment.

First, the difference between being mistaken and lying is intent. The site guidelines call for being charitable. So unless you can prove intent, don't call out someone for lying.

Second: Just saying someone is wrong/mistaken/lying turns into a five-year-old's argument: "Am not!" "Are too!" That's not a useful conversation, nor even an interesting one. Instead, supply some evidence that the rest of us can look at and judge whether you're right. (Actual evidence might even convince the person you were replying to - some of us here do actually listen to facts from time to time.)

However, they (Powerball, whoever) buy the annuity I think. If you give a lump sum, then after paying whatever taxes, would I still be able to buy the annuity?
I’m a little confused why that is relevant. Is there any payment in life that isn’t taxed?

When you interview for a job, and the salary is 100k, should they advertise it as 70k?

quite frankly, yes, but that is an entirely different conversation. :)
This isn't tax, you'll still have to pay income (or whatever) tax on the $5,800,000. This is them deciding to give you less money, and claiming with careful investment you could make $10,000,000 over the next 40 years.
I think it will always make sense to show gross salary. Various things can affect tax rate, such as 401k and HSA pre-tax withholdings, and the income of your spouse.
For those interested in projects like this outside of the U.S there is a similar decentralised version called pool together which uses the dai stablecoin for tickets: https://www.pooltogether.com/ with the code open and auditable on github too.

If you are new to crypto you can access it easily using wallets like: https://www.argent.xyz/

"Win up to $10 million by saving in an FDIC insured account."

I see that . Sounds scammy and gimmicky. Close page.

We have had this issue for sure, and it's a great point. Any suggestions to help us make it sound less scammy but that also communicates something similar?
The grand prize will be paid as a one-time, lump sum payment of $5,800,000. This is the current present cash value of a $10,000,00, 40 year annuity. The odds of winning this amount are 1 in 3,277,899,625.
For anyone that's curious, if you put enough money in to buy every single possible ticket (81B), you would get about an APY of 0.00125% per week for an annual APY of 0.06%

Not very useful but I guess if you have 81B in cash laying around, it makes sense to put your money in Yotta over some large banks! Of course that should probably not be in cash but hey, I'm not going to tell you what to do with your 81B dollars.

We need to tell Jeff Bezos about this strategy
I'm surprised the play here is to make your own bank rather than integrate existing banks. I've never worked in finance though, maybe integrating with banks is a PITA.
Well this is a lottery basically. Doubt it that you can create the margins needed for the payout by integrating with banks.

The business models here is to be a bank that raffles money based on your deposits. And they need to hold that money to generate the profits to support those payouts.

It's quite clever. This fully disrupts businesses like scratch tickets which are quite popular (haven't seen one gas station that doesn't sell them).

I actually wish I had this idea. It's super smart. My only doubt is that this model apparently doesn't scale just with holding money. Digit tried that for a while and then they start charging for their sevice.

It's much easier than it used to be, but it still sucks. Even with Modern Treasury and Plaid banks a a horrible thing to deal with.
We actually do integrate with existing banks right now. Getting your own bank charter is a very heavy lift. Maybe sometime down the road
Note that as soon as you accept any winnings you give Yotta full right to use your name and city for marketing.
We only use first names and last initials along with cities for social proof to show that people are winning.

We do allow you to be completely anonymous from the privacy settings within the app. If you don't want your first name, last initial, and city shown anywhere, you can toggle it off.

Why not make it opt-in rather than opt-out?
We find most people aren't sensitive about the first name last initial thing, and it helps us in terms of social proof. If we get complaints, we could swap to opt-in vs. opt-out.
From the FAQ

> While technically not "interest," you receive a savings bonus every month that functions very similarly to "interest." Savings bonuses are paid on the first of every month and are based on your average balance in Yotta from the previous month.

How do taxes work with these "savings bonuses". Do you issue a 1099-INT for this money earned or does this show up on a W-2G?

It's considered miscellaneous income. We issue you a 1099 if you win more than $600 in the calendar year
Does the monthly interest also count towards the $600 for the 1099, or do you also issue a 1099-INT for the monthly interest?
The monthly savings bonus also counts towards the $600
How does users being able to withdraw their money immediately affect your business model? How are you preventing someone from depositing/withdrawing the same $25 a billion times per week?
Its a savings account so you can only withdraw 4-6 times a month.
The regulators actually lifted this cap recently, so it's now unlimited most places. But this is temporary from covid.

They wanted people to have more flexible access to their funds given given the macro environment.

There is a federal requirement with savings accounts that you can only make 6 withdrawals per month. Right now that has been lifted due to covid, so there is no limit.

If you withdraw, you lose tickets so that is a deterrent to continuing to deposit and withdraw to game the system

Is there a limit to the amount of money you can withdraw at once?
Yes. This is for fraud protection reasons. The way ACH works is pretty crazy and is easy to commit fraud with.

Right now it's $2,000 per day. If you want to withdraw more than $2,000 per day, you can upload a driver's license to verify your identity (prevents fraud) and then you can withdraw up to $100,000 per day.

Sounds like a great idea, I made an account. I was looking at the official rules and noticed the mail-in option to get tickets. Was it a regulatory requirement to provide a way to get tickets without deposits?
Yeah. In order to offer prizes via a game of chance, you can't require "consideration" and so there needs to be a way to enter for free
I wonder how effective that is. eg. you can make it so you get 1 entry for free, but make it so you get 1000 entries per $1 deposited so all the free contestants get buried by all the paid contestants who have millions of entries.
Yeah the lower the dollars saved per ticket, the less valuable the free entries. You're 100% right on that point
Can I open a account if I'm an American citizen living outside of the US?
Yes you can, but to win the jackpot prize (paid by an insurance company) you have to be considered a "resident" of the U.S. I'm not sure if a citizen automatically means you're considered a resident. But you can win all other prizes as well as the savings bonus.
Your FAQ says you use a third party that draws the random numbers. Is this number drawing verifiable somewhere? Can you say anything about their techniques?
The insurance company we work with that is responsible for paying out the jackpot prize draws the winning numbers.

They have no access to the numbers users have selected, so it's completely blind.

fair enough, i guess it makes sense to have that separate, just the rng methods nerd in me always interested in how to find randomness.
I'm curious what kind of controls you have in place to ensure that the company choosing the numbers doesn't have an employee go rogue like what happened with the McDonald's Monopoly game. https://en.wikipedia.org/wiki/McDonald%27s_Monopoly#Fraud
Only two people at the insurance co. know the numbers, so the knowledge is limited. This helps because less chance of a bad actor being involved if the info is limited to a very small circle.

We would be able to spot anomalies over time in number of winners of high prizes vs. what the probabilities say, and we would investigate it if anything looked off or suspicious.

We also carefully vetted the insurance co. and the people there that we work with.

These don't eliminate this risk entirely of course, but they help mitigate it.

How can the customer confirm that the numbers are truly random and drawn live so you can't coordinate with them? It's to both your benefit and the insurance company's to not have high dollar prizes pay out. The insurance company would be on the hook for the prize, and it would cause your premium to go up.

Companies wrongfully fight unemployment claims all the time to keep their insurance rates down. It would be awful tempting for the insurance agency to send you the drawn numbers even ever so slightly early and let you alert them so they can redraw if the jackpot was ever awarded.

We want to show the customer that the number draws are truly random. We may do live drawings at some point, which could help. Would love any ideas on how we can hammer home that the number drawings are random and totally kosher.

It actually would be beneficial for us for someone to win the jackpot, and not beneficial for the insurer. The marketing benefit of a $10 million payout that an insurance company pays for would be huge for us. That's why the number drawing process is double blind. They choose the winning numbers and they can't see the picks. We can't see the winning numbers but we can see the picks.

Also since this type of insurance is purely mathematical, the risk doesn't change for an insurer if someone wins, so the price wouldn't change either. Unlike, say pet insurance, where if Bulldogs get sick more often than you thought, the insurer simply mispriced the risk.

This type of insurance is impossible to misprice. It's almost like a casino for the insurers. There is risk but no uncertainty of what the risk is and the odds are in your favor when you write more premium.

The cryptography world has a ton of ideas about this, but it's possible that most of your customers wouldn't find it easy to understand why some of those ideas are correct and fair.

A simple one (not necessarily anywhere close to the best that cryptography people have come up with) is to combine several sources of randomness in a prearranged time order and format, and use the result as input into a prearranged cryptographic hash function. At least some of those sources should be publicly verifiable, and at least one of those should be https://beacon.nist.gov/home. I can think of critiques and limitations in this approach, but it's a good start!

Edit: someone elsewhere in this thread has given a link to a more sophisticated method.

I’m highly skeptical of jackpot generation, as there has been multiple high profile examples of corruption in this process. Yotta would have to insure me this is fair before I consider saving with them, but to be fair I’m probably not their target market as high earner that already has established savings practices.
Thanks for this feedback. What could we do that would give you comfort in the number drawing process? We definitely want to address this concern, so your feedback here would be great.
Anything that either

A. Improves the transparency of the process

B. Improves the entertainment proposition of the gamble aspect of hitting the jackpot.

Maybe with a live event you can do both at once.

You can do provably fair gambling by using cryptography to show the generation was not tampered with. It was common in bitcoin gambling sites that had no other way to prove they were (somewhat) legit.
While this may be cryptographically sound(I haven't looked into it), it's not a viable solution since it won't be trusted or understood by the majority of their target demographic.
Surely it depends how they would frame it? I'd imagine they wouldn't lead with "Cryptographically secure with BitCoin .."
An auditable system doesn't need everyone to do the audit: you want it for anyone to be able to audit, and for some to do it.

It's also very easy to provide the auditing tool. (I did it, long ago. Basically a form.)

It is possible to perform "trustable" random number drawing by combining values from multiple third parties such that if any of them are fair, then the results are fair, with everyone publically able to verify the combining step.

That means all the third parties would have to be corrupt to corrupt the results. So if you can pick a diverse set of third parties such that everyone is likely to trust at least one of them, that will raise overall trust.

But you can do better than that.

You can also have people provide their own random input. In that case they will certainly trust themselves, and therefore can trust the results if they can verify the combination step.

And you can draw input from public sources that people can check for themselves, and have confidence is effectively random, in the sense that nobody can control the values. For example public blockchain hashes (as part of a combining scheme, not by themselves).

These sorts of schemes would give people absolute assurance that the drawn numbers are fair and uncorruptible, and they aren't difficult to implement.

(PM me if you'd like to discuss further. Email in profile.)

When designing a combining scheme, how do you avoid a last outcome wins situation?

If you get to choose or influence any of the inputs and (for the most part) know the others, you can influence the result. I.e. choose from a set of outcomes, or at least influence outcome probabilities.

This looks really neat :) But I do wonder how well the Premium Bond (PB) idea will work when not backed by the state (NS&I, who issue PBs in the UK, is backed by the treasury). I would personally worry that my deposit will just be used for prizes in a Ponzi scheme situation.

Another thought is that while it is true that in the UK a large number of the population have PBs, these are usually bought by their parents when they are born. I still have my PB account that was set up by my parents, but I wouldn't consider it a tool for saving. Most people's balance in PBs are a tiny proportion of their total savings. Yotta's 0.2% base rate might change that behaviour though!

Having the backing of the government like with Premium Bonds is huge. Both for marketing and for trust.

Building trust is definitely a challenge for us as a new company. Funds with Yotta are FDIC insured up to $250,000, which helps, and we communicate that to users, but people still need to trust us fundamentally.

We looked into Premium Bonds and also found that a lot of Premium Bond ownership comes from older generations. We are hoping that our UI and mobile first approach make the concept more appealing to a younger demographic in the U.S.

As a Brit not attuned to American retail banking I didn't notice the FDIC insurance element (aside: in the UK that's called FSCS Protection). Actually that's pretty huge for trust, great job :)
Yup - but people still need to trust that we actually are FDIC insured. We've had some people contact our partner bank directly to verify they are working with us, for example. But hopefully as we get some PR and more word of mouth, we won't have that issue as much.
Perhaps you could link directly to evidence of your FDIC insurance policy?
Yeah maybe there is something like that we can do. Hadn't thought of providing some sort of hard evidence. I will look into this now though!
I like the concept, but what you are offering isn't really comparable to Premium Bonds in the UK. The prizes in Premium Bonds are guaranteed every month. It's a raffle where every £1 deposited gives you a unique Bond ID. This is totally different from a lottery where the prizes are not guaranteed to be awarded for every draw.
I'm really glad to see someone doing this in the US - kudos. I remember being so disappointed to hear in the podcast that this approach was illegal in the US, and I didn't realized that changed back in 2015! I think this approach to incentivizing savings is a net good for the reasons you stated. Congrats on the launch. I wish you success!
Very interesting. An idea that has long held interest (har) for me.

I note from your comments the socially-laudable aim of attempting to help people in financially vulnerable populations. I wonder if emulating more elements of a lottery-like game would assist with this... EG imagine if I could walk into a shop, buy what looks and feels like a lottery ticket, but I've actually effectively added money to my phone-number linked savings account. I think there would be real power there, but naturally real logistical complexity also.

Totally! We have thought about this a lot. It's too heavy a lift for us at the moment given the complexity, but this is something on our radar for sure.

Appreciate the feedback.

What I had a problem understanding is the worst case scenario, specifically that wouldn't i better off by just going to Marcus or Ally? There i don't "win" anything but in the long run the yields are worth it, which I don't get from you?
Yes you are right. In a worst case scenario where you never win a prize, you do have opportunity cost because you could have earned more from a Marcus or an Ally.
But in the best case you might be far better with this option.
I think someone did the math and the effective interest factoring in the expected value of the prizes is just above 3%. That's significantly higher than what you can get with a regular savings account.

https://news.ycombinator.com/item?id=23781247

This is an awesome idea, and I intend to try it out.

I am a mathematician, and at the same time I can't resist the temptation to purchase the occasional lottery ticket. What most people miss about the lottery is that there can be utility to variance - the opposite of ennui.

Have you guys read The Lottery in Babylon

https://en.wikipedia.org/wiki/The_Lottery_in_Babylon

As a mathetmatician how can you ever justify participating in a lottery where there is a possibility of no-winners or shared winners. It just destroys any hope of any positive EV.
The point is that my personal happiness level does not only depend on positive expected gain in capital.

I gain happiness also from the miniscule hope of the life-altering outcome of winning the lottery.

That gain in happiness is occasionally worth the price of a lottery ticket.

Interesting to hear. This is something similar I do with some betting/stock buying I do.

But the odds are on a completely different level of impossibility in lottery that I just cant really get your end of the argument :/

Fair enough - I think it's a subjective thing and also depends on your current financial circumstances. I'm a starving startup founder, so the hope represents a real escape from my current financial circumstances.

If I were poorer, I suspect the happiness I gained from the lottery ticket purchases would be even greater.

If I already owned a home, on the other hand, I would value the lottery ticket hopes much lower.

I totally understand you! I'm a software engineer since 2006 and even though I followed a classical career (in Eastern Europe), we (me, my wife and our daughter) were struggling financially for the first approx 9 years.

Buying a lottery ticket from time to te, when the prize was big, made us live in a fantasy world between the time we bought it and when te results were announced. I think this thing - imagining a life without financial worries, lavish vacations and expensive toys, motivated me to learn more, try to launch a few startups and sacrifice my free time in order to try and achieve greatness.

Were those money well spent? Definitely yes (even though I haven't actually won the lottery)

The value is in the hope it creates. As a statistician, a lottery seem hopeless. To everyone else, it's about feeling that something impossible becomes possible.

Tbh lottery tickets can be a pretty cheap form of hope relative to other forms of gambling. Take a look at some of RobinHood's customers who are ”investing”. The odds seemed so favorable until they realized 95% of traders lose their money.

But people routinely buy insurance, and it's considered a right and moral thing to do. Though the math is exactly the same as with the lottery. Statistically, odds are unfavorable. But it buys peace of mind, so people pay.
The insurance is given a polarity and connection to the rest of your luck in such a way that it smooths out your risks. On the other hand, playing the lottery makes your good luck spikier. (Though there are more specific ways to say it, we could say that insurance is meant to make your life less impacted by chance -- more predictable -- while insurance is meant to make it more impacted by chance -- more unpredictable.)
(whoops, I mean "while the lottery is meant to make it more impacted by chance")
Exactly. People try to maximize expected utility in life, not expected value.
Yes, I know the feeling from the times I bought a ticket myself, against rationality.

I'm not an expert, but seems to me this feeling is also the main driver leading to gambling addiction, which ultimately leads to addicts saying things like "It's not about the money, but the game itself", after having lost a ton of money.

Wonder if Yotta can lead to the same addiction, and if so if it is then solely applied for positive objectives (i.e. saving money), or lowers the barrier to entry for other gambling schemes that are less beneficial.

We definitely don't want people to start gambling. We hope that the riskless unlocking of upside that we provide shines through as a better option than risking money for upside, even if our overall upside is lower on an absolute basis.
Life is not all about EV. Especially not monetary EV.

I own my home. It's an objectively bad investment (my tech stocks sure appreciated more than a home I bought in 2008 before the crash :) But I like the feeling that comes with owning a home.

I go out for dinner. (Well, used to). It's objectively a waste of time and money, but I still like the feeling that comes with it.

I play guitar. There's no EV attached to it (in fact, people might pay me to stop ;) but there's still an emotional payoff.

The same goes for the lottery. For some people, there's entertainment value in it, despite understanding the mathematics of it. If you've ever played poker for money - unless you're exceptionally good, you paid money to sit around a table in a smoky room. EV is negative, emotional experience is a lot of fun. (Yeah, poker isn't entirely chance, but I promise that unless you're pretty good at it and spent a lot of time learning, it's pretty much equivalent)

We don't rigorously define a numeric EV on most things in life, but we do assign some notion of fairness. You go out for dinner, but going out for dinner comes with expectations, even if the monetary EV is < 1. Basically that the food won't kill you. Similarly there are certain expectations on the lottery on the practicality of winning - everyone knows the odds are against you, but there's still an expectation that a lucky enough someone can win.

A lottery that doesn't have a winner sounds rotten and I don't think you'd eat rotten food from a restaurant, no matter how much you accept that inherent EV of the transaction is negative. There are many, many more words that can and have been written about the psychology of lotteries, but suffice to say, for many lottery players, it's not as simple as "I know that the EV < 1, I'm just playing for the entertainment value".

For example, in some cases (I won't specify for the fear of being cancelled) your chance of becoming rich by your skills is exactly zero, and you know it. Chance of winning the lottery is small, but higher than zero.
I'm the same way, I know the lottery is a terrible bet but I still find myself buying a ticket every now and then. This was one of the main motivations for starting Yotta for me.

Will definitely check out The Lottery in Babylon!

Saving USD is a terrible bet
As opposed to a virtual token?
Say that again when mortgage insurance, utilities, and insurance companies all accept crypto.

Actually even then, it wouldn't make sense to hold your e-fund in a volatile asset.

Got a potential bug report: Signed up for Yotta, and referred my wife. She added money to her account and bought tickets. I did not receive the 100 ticket referral bonus or, if I did, cannot figure out how to claim it.
The tickets get applied for the following week's contest. You should see "100 pending tickets" on the home screen of your app. If not, shoot me an email and I'll get it resolved asap!
incidentally, you’re describing a key limitation of economic systems, whereby value as represented by price doesn’t reflect holistic utility to infinitely-complex humans and human societies. it’s true of basically everything, including stocks (efficient markets and all that), and forms the basis of a material critique of laissez faire capitalism.
This is interesting.

The way I understood the work of von Neumann and Morgenstern on game theory, there is an extensive discussion of utility and the derived ordering on preferences.

I interpret recent work on behavioral economics as building on their work to call into question the claim that one can easily estimate such a utility function for an economic agent in a manner invariant to the internal state of that agent.

This train of thought seems like it should leave laissez faire capitalism in the dust.

This is interesting :-)

Is there any reasonably accessible literature on this topic, in particular the latter idea of not being able to estimate an agent’s utility function?

I'm not particularly well read in economics, and have not read anything that specifically addresses the difficulty of estimating utility. My view is rather derived from my readings on economics and related fields. The material that stands out the most in my mind are:

1. Von Neumann and Morgenstern's book (particular the sections where they develop the notion of utility) is pretty readable - https://www.goodreads.com/book/show/483055.Theory_of_Games_a...

2. The Economic Naturalist (https://www.goodreads.com/book/show/629238.The_Economic_Natu...). It is a great compilation of economic edge cases which show that the notion of utility is not so easy to capture using the standard "narrowly self-interested economic agents" world view. It requires a lot of subjective interpretation.

3. The Honest Truth about Dishonesty (https://en.wikipedia.org/wiki/The_Honest_Truth_about_Dishone...). Shows how contextually dependent utility (if it is at all quantifiable) can be.

4. The body of work around the Iterated Prisoner's Dilemma: (https://en.wikipedia.org/wiki/Prisoner%27s_dilemma#The_itera...). In particular we can see how the dynamics of simulations using rational agents diverge from the dynamics of experiments involving actual humans. This suggests that the utility assumptions used in economic analyses do not reflect whatever notion of utility that could actually apply to human behavior.

yes, i'd heard it talked about in relation to environmental economics, and about externalities in general, e.g., "how do you price in externalities like pollution in relation to our emotional enjoyment of nature?"

utility is neat in theory, but seems to be messy in practice. it's one thing to spell out the relationship, but another to calculate an analytic solution (from my limited mathematical experience, navier-stokes comes to mind in this regard).

Is it worth buying his "Ficciones" compilation ? I have heard about the Story "Funes the Memorious", which is also included, and have been Interested in reading it since. Altough I still have 2 or 3 more books to read.
Yes, definitely worth it. There are some great stories in that collection:

- The Garden of Forking Paths - Pierre Menard, Author of the Quixote - The Lottery in Babylon - The Library of Babel - Funes the Memorious - The Secret Miracle - Three Versions of Judas - Death and the Compass

You will not regret it. :)

Thank you :) I almost bought it on impulse, and I think I'm going to order it today.
Can I transfer my deposit out, then transfer it back in to get additional tickets?
No - you would lose tickets on the withdrawal and get new ones on the deposit
Section 14 of the official rules says that you can write for a list of winners. https://www.withyotta.com/official-rules

Does that mean that one could essentially get a list of your customers (that won in a particular week) if someone requests the winners every week? Over time one could figure out about how much each customer has in their savings account.

What information is released on the winners list? I'm not sure if I'd be willing to sign up for an account where my personal information would be released publicly if I "won" a 10 cent prize.

We only use first names and last initials along with cities for social proof to show that people are winning, and we only show when a ticket has won a notable amount so there's a fair amount of randomness to who shows up (currently >$10)

We also allow you to be completely anonymous from the privacy settings within the app.

Thanks. Can the information about the prize cutoff be added to the official rules or the FAQ?

Based on this, I think someone with $10000 deposited would appear in the winners list about 4 times a year, assuming those that win the $15 prize appear on the list of winners.

Yeah we will update this. Thanks for the feedback
You could also let people create nicknames for privacy.
I like this idea. Thanks for the suggestion
I am so confused. Are you saying your company will reveal personal information, without a users consent? What if the user doesn't want to appear on the winners list? What if they withdraw their consent at a later point? What if they live in California (CCPA)?

In the UK, no such list is published. Nor is it published for lottery winners (you can opt to be anonymous, which is the default option).
