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.
