The main problem is which industry will try to adopt the technology that has already used by crypto? I have seen so many projects have been using them all and they tried to combine it with the technology of crypto.
But till this time and none of them have created such a useful product. Basically crypto can be used to change the economic system.
That's it, I've seen that Venezuela is doing their best to adopt the tech and use of their very own Petro coin.
But it looks like its failing because of many factors. Most of those industries can change forever after adopting crypto, blockchain technology and other things related to this innovation.
