OT but I'm in a situation where I have hundreds of different altcoins on a handful of exchanges. I'm looking to move these into my own wallets but it seems that I will need to get so many different wallets that it's not worth the hassle. Why isn't there a wallet which can handle all kind of cryptocurrencies? The most I've seen in one is like 10.
As someone working on cryptocurrency wallets its a much more difficult task than you think. First you'd have to be compatible with multiple chains, then you have to support multiple contracts on those multiple chains.
Then theres tokens that start out as ERC-20 and eventually want to move to their own chains, which means your wallet is gonna have to be responsible for the swap.
On iOS specifically theres distribution issues where some cryptotokens are allowed and some aren't.
Also one way that wallets make money is by listing fees, so if you don't pay up forget about your coin getting listed. I heard from Vertcoin community that Exodus specifically was asking for 200,000 USD for a listing
Coinomi supports a surprising number of coins, and I have used it as an intermediary. I'm not sure that I would use it for long-term storage without knowing more about the company.
Yeah, nah. Dont store your coins in sites or dapps or anything that you do not control 100% yourself.
The best option for folks today is exodus.io, which is a multicurrency platform-ind js wallet. You control 100% of the key material and control the funds.
There is also jaxx and coinomi.com that can act as multi-currency wallets.
I built something like this with a postgres database of transactions, a python script that scrapes the coinmarketcap api, and influxdb + grafana. It works well and suits my needs.
How were you able to update the database frequently with python? I’m trying to basically have a database that mirrors historical data on an exchange, that also updates every 5 minutes — I’m trying to decide between a node server / python aws lambda.
This is the first Mac application that I have come across that does not support my version of Mac OSX (10.11). Too bad it doesn't work in the browser version of Blockstack.
We've been getting sporadic reports that people are using `http` vs `https`. It _should_ auto redirect you to `https`! Apologies, we 100% intend for every user to use https, will dig in further :)
That's odd that coinsapp claims to be "one of the first apps built on Blockstack ever" but Blockstack does not even mention coinsapp in the "Featured Apps on Blockstack" section on the main page.
Yeah, if you are in the Blockstack browser, you'll see it right there on the home page :) there's a delay between the homepage updates (marketing) and what is live within Blockstack itself
Wow, well done. This looks really polished. One minor nitpick I have is just on the landing page.. you have these gradient circles for each feature which doesn't really add anything to the content. It would be better to have icons or even remove them.
I gave it a quick try - Coinsapp only seems to support a very few coins while there are plenty of portfolio apps out there that include pretty much every single altcoin out there (Blockfolio comes to mind).
For me, this is not yet the killer app that lets me track all my coins that are spread around various wallets and exchanges.
One more note: not all coins are bought, some are mined. It would be nice to have an option when adding a holding that it has been mined and not bought.

What language was used for the backend and frontend? I'm trying to make a web interface for a small project but I think I love Java too much to learn JS or HTML...
What a pristine example of next level stockholms syndrom! With that attitude it might benefit you more than anything. Theres nothing that gets me to not hire someone than the person saying “Im a {language} developer”
Might be the opposite, for example there are some languages I consider a waste of time and refuse to learn. Mainly languages too close to my current skillset, as I feel there are other languages that can teach me more with the same effort, or languages I consider downright badly-designed.
The best way to break a couple up is to hire a hacker to do it for you. Hackers can hack their text and whatsapp messages which you can always use to your advantage, dig up dirty secrets from victims' phones, social media accounts, emails etc...and the good thing about it is that they will break up and nobody will suspect you caused the break up. visit: darkwebsolutions. co

[ 2.3 ms ] story [ 119 ms ] threadBlockstack is new to me. I've just been starting to dig into Ethereum. Would be really interested to hear experiences / comparisons between the two.

The Ledger Nano S supports "apps" that can provide compatibility with many coins, and could theoretically support many more. (https://www.ledgerwallet.com/cryptocurrencies)
You can find more examples on google.

if you're concerned about security just use the official client

The idea there is just to have a simple portfolio bookmarked without login, emails, passwords cookies or an app installed.
I'll write a separate Show HN later. Sorry for the shameless self-ad.
How long did this take you to make?
