After some thinking about it, I think the idea of using blockchains and stuff for some sort of currency is not necessarily a stupid idea. A way to exchange a set of equipments and time to mine what could be said as a digital ore makes sense. However, since they can somehow be exhanged to a real-life currency, they are basically a form of money, and we know what will happen when people join that game.

For NFTs though, I had no idea how they work, nor do I care.
