How will it happen?
Will it just suddenly one day drop to $0? Or will be a slow painful bear market finishing near $0 but never quite reaching at? Some believers will never sell no matter what price ??
What do you guys think?
I think Bitcoin cannot reach zero (not in the next decade anyway). I would rather not sell anything for 10 cents, not worth the trouble. If the entire stash of Bitcoin is available for 1k I would buy it even if the world considers it worthless.

haha, exactly. bitcoin will never become cheap. and even if it gets on the path of getting there, it will take decades to become worthless. because we are all waiting to sell our clothes to buy bitcoin dirt cheap!
and there is no reason to get on that path, bitcoin is growing everyday.
