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 that the cryptocurrency is a testing ground for the future new financial system, the alpha version. Once cryptocurrency will replaced a monetary unit but will be centralized and managed by banks.
