Anyway, the up swing is impressive now and can't be dismissed as normal volatilty:
There will be a big drop at some point, no one really wants to sell when it's rising like this. This sort of upward movement is exactly why a lot of people have bought Bitcoin. Trying to time the top will be hard though. I imagine a subsequent drop of ~25% would be likely.
It's fun to be back at a time of thinking about when to sell again.
