Well, the tandem of crypto currency and gaming industry surely is exciting since there are many gamers in different country. But I think, the bitcoin should not be use for payments only or to buy items and/or peripherals in the game. I think there should be atleast other game wherein they can get bitcoin, maybe the best is the gambling but a pvp type of game.
That is possible too, actually the author mentioned like a battle royale game that you earn bitcoin when you hit other players, and vice versa.
This new platform, gaming, is very useful for spreading bitcoin, and is actually one way we can invite gamers that are nonbitcoin users, surely they will be interested. Not only that, bitcoin could be mainly used as a payment method or the main currency used in online games. Not bad. I am sure gamers will agree to this one.
