Right now, many of you are saying that this kind of growth cannot last forever, and that may be true. However, it is true without a shadow of a doubt that Bitcoin, if successful, will be worth a great deal more in the future, and to get there, we simply must have dramatic rises such as the current one. Thus, crashes will not last.
This is not 2011. The end of the rally will be more like January or August 2012. A panic sell happens at $500, for example, and for two months, people will be depressed as the price just slides down, but overall, stability is much better, and liquidity improves in the markets. The fall stops at $350-400, and then we have a consolidation period where we rise into the mid-high $400s and stabilize for a few months. Then, good news arrives in the form of increased adoption, beginning the next leg up.
The 'bubble' will not end with a bust, it'll end just like the previous two 'bubbles': more adoption, better fundamentals, better liquidity.
I agree, there's more down and ups to come, but as usual we'll end up much higher off. I can't hope to predict at what price those tops and bottoms are so I'm holding tight, as I have done since $14.
