I cant wait that time will come the bitcoin will be the next decade. For the most popular is the social media because of the millennial generation. I think the next will be the cryptocurrency. When you age the millennial generation must of them is around 14-20, that ages are most focus on games, gang and social media. Time will come they mind focus on how to they earn money. There are big possibilities bitcoin will be the next one.
