Saving money in a savings account is like putting money in a pocket with holes. Banks only give you interests that are lower than the inflation rate. Its how they make money. You are better off investing in ventures (Crypto currency) that give a return higher than the inflation rate.
In my country, banks give an average of 15-18, and even 21-23 percent per annum, for depositing money. This, in principle, a good income, even given the small inflation. This, after all, is stable and guaranteed profit. If the bank is a state bank, profits are guaranteed by state assets, and if the bank is commercial, then there is a guaranteed deposit fund from which money is returned to depositors if the commercial bank goes bankrupt. True, the guaranteed amount of payments is about 8-12 thousand dollars. However, vseravno, a guarantee of return is.
If you have invested your money in the crypto currency, you are fully responsible for their safety and assume all the risks of their loss. And there are a lot of such risks. And their own mistakes, and hackers, and just the riskiness of crypto-currency investments. Here you can make good money, and you can lose everything.
Those rates are higher than the current inflation rate? How can banks afford to give such high returns? Most banks are giving returns on fixed deposits that are slightly lower than inflation.
Yes, the important part about this is the risk. Risk is much higher with crypto so naturally, returns have potential to be much higher as well. The current fluctuations between 6-8k are evidence enough of that. If you just get on while it's low and don't use leverage, it won't be risky though. Even for the riskiest assets, the risk is only as much as you allow it to be.
