What do you think are the main problems of cryptocurrencies that stop them from becoming real money and real medium of exchange (volatility, etc.)?
Actually more of the trader's really like the volatile price of bitcoin if bitcoin price is stable it will not attract more investors to came in.
You can easily earn profit in bitcoin because of that and this is also the reason to lose if you are not careful to decide when to buy.
If you just want a stable crypto currency then you can choose USDT.
