I know crypto by the end of 2017. I learned a lot about crypto but I still do not know what it was born with a mission. I have heard many people say that crypto will change the world, crypto will be the future currency to replace real money, crypto will be applied to life, .... I still have not seen many things Applying from blockchain technology instead of paying for some co-payments between projects.
I think it will not be easy to replace the current financial system, even though our future is a digital economy. But of course blockchain technology will be closer to everyday life, even though it will take a long time to be adopted massively, because blockchain must first get legality globally.
