There is a minimal chance that this will happen but of course it could be possible, the bitcoin is already so big that it cannot disappear right away in my eyes.
It would take years to destroy it fully..
I don't think that this is going to happen either because bitcoin is now strong and that is not going to let the whales happen for they are now getting their main source with bitcoin. And I doubt it that this is going to make possible to happen in the future. It will even make the fiat currency to disappear but bitcoin won't disappear.
