Bitcoin can disappear?
Things don't just suddenly disappear, we live in the real world.
And if bitcoin is a scam, what will happen in world?
It is not a scam.
People will panic?
Only the average Joe panics over nothing.
How could bitcoin disappear? I don't think that could happen. It can reduce in value to 0.01 cent but that doesn't mean it will vanish and not be available to be used as a currency.
Exactly. Bitcoin can't just disappear for no apparent reason.
