A lot of people are talking about how the falling bitcoin prices is making money evaporate, as though Bitcoin is somehow eating up life savings. The only thing that is evaporating is electricity and overheated GPUs, everything else is just changing hands. If you draw an imaginary boundary around all of the people playing the bitcoin exchange game and consider all of the real dollars that they have put into it, there is no sinkhole where dollars are disappearing into. It's just they have redistributed there wealth between the players. It's like playing poker at your buddies house, you came to the table, made a bet, and someone lost and someone won. The people who bought at $30 lost, and the people who sold at $30 won.
Similarly, there was no money tree when the price was ramping up. If you made money, that was late adopters putting cash into your hands. A purely speculative commodity trading environment (which is pretty much what Bitcoin is if you get rid of mining and the constant flux in how many people are playing) is just another type of poker. You are gambling on the actions of other individuals who in turn are gambling on the actions of you and everyone else. In a sense it's more pure than poker because if there is no fundamental value then the game is purely psychological. There is some data to be studied in looking at how many people are joining in based on media attention and whatnot. But I think that the sheep are the minority, and most players are out to make personal profit.
Also, why can't I post anywhere else yet. I've been stuck in this stupid forum for too long.
There might be some positive things with the price drop. People holding thousands, if not tens or hundreds of thousand bitcoins, can definitely make the price go up. Until they found their 1000% profit is enough and start selling, and the price starts dropping. I guess that is what happened by the end of July, accompanied by the mtgox password leak, mybitcoin going down and losing coins, and that polish exchange accidently deleting 17k BTC.
This raises the question, how many private keys are lost?
Either way I am not concerned of the price, I simply do not consider bitcoin an investment. I can keep $100 on a reliable exchange, and buy bitcoins when I need them. Merchants can set up a system to auto adjust prices and instantly transfer to an exchange to sell the coins, to make sure they don't lose on the fluctuation. Luckily I can make use of free SEPA transfers. I hope more options become available so people are only subject to a 0.5% conversion fee at the exchanges.
