For another five years, everything will be in the same format as now, except that the blockchain system will gradually adapt and update.
And I think that in 5 years everything will change very much. To date, cryptocurrency and crypto projects are still difficult in everyday use by ordinary users and require special skills and the ability to use special computer programs. All this hinders the process of mass use of blockchain technologies. But soon everything will change!
Now, people who follow technologies are much easier to understand, cryptocurrency is not difficult, the main thing is to read everything and follow the trends
It still seems to me that while cryptocurrency does not become a simple technology for the user, such as the Internet or social networks today; cryptocurrency will not be used everywhere. But as soon as easy and understandable wallets and clear and simple methods of payment and purchase are made, fiat money will go into the past and the whole world will use only cryptocurrencies.
