Cryptocurrencies are digital currencies. Just like regular FIAT currencies they can be traded, saved, or used to gather interest. The large difference between FIAT and cryptocurrencies is that banks can create extra supply of FIAT currencies, which results in inflation. Cryptocurrencies generally have a limited supply of coins where additional coins would be released with the use of mathematical equations. This is implemented in such a way that there will by definition exist a certain maximum number of crypto coins, along with a predetermined degree of inflation.
