Nobody knows. Here's an interesting thing about the market. If it were widely known that bitcoins will increase in value to $500 by the end of the year, everybody would buy bitcoins until they increased to $500 right now. The current market price is exactly what most people believe bitcoins are worth, or will ever be worth. Yes, some people believe they will be worth more, but the reason they are able to buy them is because other people are selling them, believing they will be worth less. The weighted average, minus a few technicalities, is exactly the last trade. BTW, I like your sig.
