I was rewatching Ready Player One earlier with my nephew and this thought came to my mind when I saw the prize money. If, for example, we live in a virtual world (however you describe your understanding of a virtual world) do you think we will only have one currency to use and that is bitcoin? Or will we still have different coins (altcoins)?
I think that depends on the game and the rules that are imbedded, the bitcoin would be very significant and would put a lot of publicity, it is valid because it can highlight the qualitative value that many represent. But to be generalized worldwide, Bitcoin would be ideal.
