Why does there need to be a crash?
Why does there need to be a correction?
Bitcoin is not a stock.
As long as it continued to go viral, and adoption increases, its value will as well.
This is why all the smartypants fiancial guys I know who told me I was an idiot for not selling at $150 currently have their feet in their mouth.
Bitcoin does not behave like anything we have seen before.
Its something completely new.
I don't believe there has to be a crash but I do believe there will be a correction. The reason I believe that is because the bitcoin price follows some of the same principles as the stock market, most notably supply and demand.
Stock prices are like a rubber band. When they go far in one direction they snap back in the other direction. This doesn't mean that the general direction has to change though. But if there is too much interest in one direction there is the perception that the commodity is either overbought or oversold and people invest accordingly which takes the price to the other side.
