Interesting to see spillover effects from the bitcoin drama over the past few days
I love it.

Diversification of investments is awesome.

Exactly. Recall the lessons of the Dutch, they bought both blue and red tulips.
Oddly that mania lasted less than 12 months. Bitcoin has been on the rise for years, is used for more than decoration and won't rot...
But Bitcoin is a gamble not an investment - its value may be 1000% or 1% of its current value next year, and neither of us can really predict that. Sure I own some (I made like 100% so far), but its a lottery ticket.

I'd say that investing in a high growth startup is a gamble, but investing in 100 is an investment.

Which links to your diversity of investment thing.

If you invested in 100 startups in the same niche, for instance 500 bitcoin exchanges, that would not be diversified. You would be betting on the same business model.

If crypto currencies are discredited - the buyers today get burned by the big crash and never come back, or laws change to make it too inconvenient to bother investing in (all the exchanges are pushed into he black market), then the litecoin price will dive like bitcoin and stay there.

> its value may be 1000% or 1% of its current value next year, and neither of us can really predict that

True enough, but then we could say much the same thing for the fiat currency of your choice. (Except maybe the CHF? ;)

No. All significant 'real world' currencies are tied to the economy of a nation-state or nation-state-like entity.

Bitcoin et al are free-floating in that regard. To see how this makes a difference, consider what would happen if one of the early adopters were to sell 100K bitcoins right now.

(I'm not arguing that Bitcoin is somehow less volatile than fiat currencies, here, but...)

The values of "Real world" currencies is quite (not totally) decoupled from the intrinsic value of the issuing state's economy. See Zimbabwe for a recent object lesson - still plenty of economic activity and trade going on in the country, but hyperinflation happened anyway. "Real world" currencies are much more tied to emotional attachments (or lack thereof) to the currency and faith in its issuer.

If you've ever tried your hand at forex speculation, you'll be very (perhaps painfully) just how much the relative values between fiat currencies is driven by emotion (and the stop-loss orders of other speculators.)

Shares and currencies...

In theory, analysts and professional traders incorperate everything they know into bids for shares, so that the current share price 'prices in' everything publicly known about a share at the current time.

I quite often talk to people who have a share portfolio, and buy mining shares because they think international demand for mining is going to rise. But the share price already reflects that because pro investors and analysts though to it first.

So really, when you buy a share, unless you have some extra information, you are making a bet on variations due to things no one knows at the time - it's simply a gamble.

Don't get me wrong, it's not a terrible idea to buy shares - if the economy grows, the FTSE grows with it. If you buy luxury goods manufacturers and insolvency companies, you can hedge. But if you, as a private individual, think you can make money day trading (in your lunch break) against the highest paid experts in the world, well you are kinda nuts.

A friend put together a database of tick data for every currency pair in the world, for a spread of different brokers. He examined the data, and found that at last in the 3 hour / day interval, it appeared statistically random. You can bet on a random variable if you like, sometimes you will make money. I prefer to put what little money I have in passive funds, and hope it beats inflation^.

^That said, I'm cashed out and 400% ahead following this bitcoin bubble. lol

Technically you're correct, but realistically there is a very very small chance of that happening. And the chance of bitcoin changing it's value in the next year significantly, compared to fiat currency, is much higher.
I could reasonably predict that the USD will have roughly the same purchasing power next year as the current. Same with EUR.
Bitcoin could become predictable like that, or at least not matter so much if it wasn't compared to other currencies... People think in terms of I want to buy $100 worth of this in bitcoin.. -- but when vendors start having flat BTC prices tha t don't fluctuate against the dollar value, or ONLY accept bitcoin, etc... then it might stabilize a little more and become more of a true currency.
Is it still worth unleashing a miner on my lappy to go spelunking for Litecoins, or has that ship sailed too?
On a laptop forget it, difficulty is way too high.
How about a brand new MacBook Pro w solid state memory?
When the whole bitcoin craziness started, I decided to go with Pascal's Wager and participate in a small way. (Note that I'm very sceptical on the whole cryptocurrency thing.)

My assumption was that, if bitcoin doesn't blow up for technical reasons, then there must also be some merit to the runner-ups. So I started mining litecoin with my little quadcore desktop machine.

That was five days ago and already I notice that my bang-for-the-kilowatthour is decreasing rapidly.

Everybody and their grandma is mining litecoin, and the smell of impending speculative crash is getting stronger.

Don't stress yourself over losing out in the gold rush. This bubble, like thousands before, will pop and you'll be there to give joking explanations of what happened to less technically inclined friends.

Noob here. Are the various crypto currencies floating around exchangeable via a trading exchange of sorts?
BTC-e is the most popular. I believe Vircurex[1] handles the largest number of cryptocurrencies.

Is there a cryptocurrency index anyone has made?

No, they all are, and frankly, I am putting the following line in my hosts file until you all grow up a little and go discuss your toy currencies somewhere else

Aww did you sell your bitcoins early :S
Someone needs to grow up, that's for sure.

"Don't be discouraged if what you produce initially is something other people dismiss as a toy. In fact, that's a good sign. That's probably why everyone else has been overlooking the idea. The first microcomputers were dismissed as toys. And the first planes, and the first cars. At this point, when someone comes to us with something that users like but that we could envision forum trolls dismissing as a toy, it makes us especially likely to invest."

That's quite inefficient. Your browser ( and any other apps ) will attempt to connect to your legacy IPv4 localhost, time-out and fail, assuming you don't have a web server listening there.

Better to black-hole with an unroutable address. Try [::].

Will it really be a timeout? I thought the OS will send back a RST packet on ports it doesn't listen.

When MT-Gox accept it this should legitimise it either way...
It is on their TODO list but they don't have a date and it's not coming in the near future... so it's not clear if this will happen.
Why "unlike BTC"? (serious question!)
not ponzi but 'pump and dump' and that label is apt for bitcoin as well
A Ponzi scheme is well-defined. Bitcoin is well-defined. The definitions are not the same.
That doesn't answer the question. LTC is also well-defined (it's almost identical to BTC) so how is it a Ponzi scheme if Bitcoin isn't?
If by LTC you mean Litecoin---litecoin is not a Ponzi scheme, either. Like BTC, it does not fit the definition.

Even if the creators of BTC or LTC were intentionally setting out to defraud people, it would not be a Ponzi scheme.

Don't bother with that article on wikipedia. Like so many, it doesn't pass the sniff test and completely fails wikipedia's own guidelines on impartiality. It contains complete weasel wording like "Additionally, people often complain". It reads like it was written by a bitcoin promoter.
that's not wikipedia.
Ah, sorry about that. I saw the standard formatting and had just assumed.
It's going to be interesting. There's inherently no technical difference between LTC and BTC (block intervals are not drastically different in practice, and nominal count of coins is meaningless). Network effect-wise, Bitcoin has much more hashing power (and thus resistance to 51% attack) than Litecoin, but it is also more valuable one, so it also does not matter much.

I don't buy there's any "diversification" in holding both LTC and BTC. The technical and legal risks are mostly the same. To me, in the long run, it's more profitable to put 100% of your money in the most liquid of them, which is currently Bitcoin. Simply because people want one money: one most marketable, most widely accepted asset.

LTC is still valuable because we are in a very early speculation phase and most folks got used to presence of both gold and silver, and there's very strong incentive for recent Bitcoin miners with video cards to pump up LTC (as that's the only thing to mine on their equipment right now) and sell out for Bitcoin while they can. Either Bitcoin or Litecoin must pop, there's no economic reason for them to stay in some balanced relation. I bet even gold will largely lose wealth as it's moved to Bitcoin, but then gold has very different risks and features, so it may find its balance with Bitcoin.

> there's no economic reason for them to stay in some balanced relation.

Actually, there might be. The fee needed to get a bitcoin transaction into the blockchain is determined by a market, and it is a flat number, not a percentage of the transaction. If bitcoin succeeds, it may not be practical to use it for smaller transactions.

It's neither a flat number, nor a percentage. Fee is not hard-coded in the protocol, everyone can decide on the fee himself. Users decide how much they want to pay and miners decide how to prioritise transactions. The fee is freely floating in both LTC and BTC, no difference here. The only practical difference is liquidity and it is produced only by network effect which tends to create "one of a kind" winner in a competition between very similar networks.

Part of this rise is likely due to the proposal of Mike Hearn, a core developer and Bitcoin Foundation officer, to start "redlisting" (marketing-friendly word for blacklisting) wayward Bitcoin addresses.

How someone who has been around the Bitcoin world for so long doesn't understand the importance of the currency's fungibility is beyond me. If you make one person's Bitcoins worth less than another person's Bitcoins, then we all lose.

Hearn only proposed there be a discussion on the matter, he definitely didn't seem like he was pushing either way.
Yes, he proposed the idea for the second time in a year "just for discussion". And the first time he proposed it, he definitely and very explicitly argued in favor of it. If he's more subtle this time, it's because he's learned this is an issue that is deeply important to most long-time Bitcoiners, since it's an assault on one of the most fundamental of Bitcoin's properties.
Wouldn't redlisting be possible with litecoin too?
Sure, but there are no influential core Litecoin developers repeatedly proposing that they do it to Litecoin.
Litecoin could be the spark that causes the Bitcoin crash. Hear me out.

Method: litecoin gets major news push as the "new Bitcoin", people sell out of bitcoins into litecoin causing Bitcoin prices to crash overnight.

Needed: a very fast way to move from bitcoin holdings to litecoin.

If someone makes that it's game over for bitcoin.

> Needed: a very fast way to move from bitcoin holdings to litecoin.

There are many very easy ways to quickly move from Bitcoin to Litecoin. On btc-e.com, for example, you can sign up and be trading Bitcoin>Litecoin within an hour or less (the time needed for Bitcoins deposits to clear).

Right, so now all we need is the mainstream news push.
