There are games out there that is using blockchain technology.

As far as I know this is not a new thing. There is this game I've read about that while you are progressing in the game, you will be able to mine cryptocurrencies. That I think is the future of gaming and cryptocurrencies since the world is slowly shifting into that kind since games nowadays are being priced with a lot of money, in the future it will be a stable job for a lot of people not just the professionals.
