In 2011 the analogy you just used worked perfectly. It needed some modifications though:
- Burst and bust work on different time-scales that do not scale by the same factor when comparing to historical bubbles
- There may be psychological delays on market state changes that are a human factor and therefore do not scale with the speed the market has otherwise
- There seems to be an instability before a bust sets in which may be chaotic in nature: bubbles are fed by an absurd behavior, namely a fast positive feedback from price curves to demand. The short-term price development may affect interest and thereby the behavior or onset of the bust.
And there could come the dude with loads of money and just push the identical game to a higher price... remember we got no decent-sized shorting market here. I'm not betting on this, I believe you're right and a bust is too likely to risk holding BTC right now.
