I believe in crypto currencies and the idea of a decentralised world attracted my attention in 2017. Especially, the finance industry needs a fresh breath and in my opinion blockchain and some crypto currencies can refresh the general finance industry.
This.
Decentralized money will rule the world and future money won't be the same as current fiat currencies 100% sure about it.
You even can check out statistics - more and more younger people use crypto and elder generation on the other hand tend to avoid it.
What does it show? That fiat users are dying out.
