Bitcoin should have been the petty cash of the Internet. People should be buying music tracks, in-game items, and junk food from vending machines with Bitcoins. But, as discussed in a previous topic, it doesn't do small or quick transactions very well. That may not necessarily be a bad thing.

Here's the rub: A price fluctuation at one exchange will always affect every other exchange. If Bitstamp drops by $50, someone is going to buy at Bitstamp and then sell at some other exchange in order to take advantage of that. That means any exchange that manipulates the market will literally be manipulating the entire Bitcoin market. There's no way for outsiders to know the difference between an artificial, manipulated price spike and a true increase in value. So if you see bitcoin rising sometime in the future, beware buying into it: you may be buying into a manipulation.
I don't know whether this problem is solvable. Even if America enforces regulations for American bitcoin exchanges, the rest of the world won't be playing by the same rules, and it only takes one dishonest exchange to mess with the global price. I'd like to know how the regular stock market deals with this. Are all stock exchanges regulated worldwide? Is there such a thing as a dishonest stock exchange? If so, how is that dealt with?
