I am sure that the cryptocurrency will very soon enter the life of every inhabitant of the earth and will remain for a long time. Cryptocurrency does not stand still, it is constantly evolving.
Perhaps it will be a little different, blockchain will firmly enter people's lives. It will record all possible documents that will help to avoid falsification. As for the coins, they will remain Internet money. But they will help to improve existing payment solutions: visa, mastercard etc.
These things will always we wanted, if we use cryptocurrency as payment system maybe we won't see a crash in the market. However, many of us who uses cryptocurrency as investment place so as there is a concern when we still hold it. It's not wrong indeed, because the prices movement is really worth to use for gain money but an impact we are feeling it now. All we know, visa, mastercard, paypall etc are a place for payment system only but not with cryptocurrency seems like just a little person who uses it as payment system and most likely they uses as investment place so I think it will be hard to believe cryptocurrency will be use as payment method.
