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)?
Get out of dreams and go to work.
Now, let us assume that we live in a virtual world, I would like it to be free from currencies or money. Desire for money is the root of most of the human problems.
