That's a bold prediction,
I predict that gaming could see a huge uptick in crypto-currency usage. Could you imagine a game like Grand Theft Auto or World of Warcraft utilizing a crypto-currency rather than an in-game artificial currency? You could create entire in-game economies with real life value. People could actually make a living by playing games full time as scary as that sounds.
Could you imagine the moral implications of someone robbing you of crypto-currency in a game like GTA or some survival game?
I just think there's some very creative use-cases for crypto-currency that will pop up over the next decade.
