No answer about th e end because the If is not likely to happen... It's like you saying If a "US dollar goes to Zero"
So long as there are people believing in it, then you wasting your time expecting it to drop to Zero.
It's like waiting for a ship at the airport.if bitcoin goes down to $0 will there be other coins that rise up in it's place?
Bitcoin is the GodFather of Crypto... Just look at how the market reacts when Bitcoin sneezes, all the market catches a cold
how far down are you thinking this bear run will take bitcoin? $1,000? 500? Less?
you should really worry about price everyday or-else you will get anxiety disorders for nothing...Bitcoin took almost three years to reach $1000 in 2016 after going past $1000 in 2013 and dropping to hundreds the following couple of years
