"What do you do if Bitcoin fails?"
If humanity is too dumb to realize the potential of #Bitcoin and fails to accept it as the solution for our corrupt central bank system I'll go down with this ship.
Seriously, I'll drop out and have a small farm with 2-3 chickens or whatever.
The amount of monetary energy in the world that is looking for a store of value is huge.
#Bitcoin is the answer to that demand.
