Someone is massively profiting from these swings. Whether it's MtGox's flaky servers or DDOS or whatever. This isn't the behaviour of a grown-up currency.
I have no doubts in the sentiments of buyers right now but this kind of volatility is getting me worried.
This isn't a grown up currency. It's just the beginning if Bitcoin is to be successful. I think in the long run the chances are pretty good.
