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 you're confused as that movie is all about a virtual world which is not reality, meanwhile bitcoins is described as a virtual currency but it's real. I don't think one needs to wait for virtual world, as many countries are getting their own virtual coin, and bitcoins dominance is growing. I don't think one currency is enough for the entire world, there'll always be room for more currencies.
