How will it affect your life if Bitcoin price comes to zero per Bitcoin one day? I have seen most of discussions related to Bitcoin price on pessimistic side only. But we should look at all the possibilities.
I would be so happy because if the price of BTC is going to be zero I can then buy a million of the coin without using money. Well, jokingly aside, I think you mean what if one day BTC is going to be worthless or just forgotten by the people and is wiped out from the face of the Earth. So what if this will happen? I think the first question is: Will this happen? And I don't think so...that is already impossible.
