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 cryptocurrency is not to replace money, cryptocurrency is like electronic money, but you can use it for investment because it has rising and falling prices. crypto cannot replace money and crypto only wants to be electronic money.
