All I'm stating is that I do not think the price will reach exactly zero. Of course it's a crash, and of course shorting it is profitable during this, I was short myself in it for a bit.

But the bubble has supposedly popped many times, keep in mind Bitcoin has had crashes far greater than just 50% before (closer to 90% has happened multiple times, see https://en.wikipedia.org/wiki/History_of_bitcoin#Prices_and_...). So if this is 'the' bubble pop, rather than just another large crash, will remain an open question for quite some time.
