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)?
Speaking of cyberspace, anything may happen, especially in the mind is bitcoin, no one will laugh if bitcoin becomes an official currency, in the real world, many use bitcoin as an easy and effective transaction tool.
