Bitcoin can disappear?
And if bitcoin is a scam, what will happen in world?
People will panic?
In this time, i don't think that it will be happened, because recently Bitfinex has been hacked, and it disappear a huge number of the people, but still people are using it, and also doing trading.
Secondly, if bitcoin scam, so nothing bad thing happen in the world, because when bitcoin was not introduce in this world, but world still remain it.
And third, people will be panic, but not for bitcoin, only for their losses, and after time passing, they forget it. And i think so bitcoin will be come on an other Crypto currency.
