First off, even if he was the creator this is not possible with the blockchain. Just to answer your question, if it did happen. It will make headlines for sure. The rates would drop and everybody will leave bitcoin.
absolute nonsense. it is possible to burn bitcoin, that means to make them unaccessible forever. why would it make the rates drop? if demand stays the same but the supply goes down, then the price usually goes up. i see no need to leave in such a case.
The price will go up, because one of the "uncertainties" in Bitcoin would be removed and Bitcoin will one again get massive media exposure. It
is not common for people to destroy $ 743 000 000 US in one day.
.... The demand will not stay the same, when a major event like this
happens. If this happens, we would see record prices.
