Various economists are already warning about the possibility of global inflation in the coming days. If something like global inflation happens then I think keeping money in the bank is risky. Because during inflation banks are in debt in various ways and those who give loans at that time also refuse to pay the bank loans, so keeping money in the bank at that time is a more risky job. Because banks will declare themselves bankrupt if they are over-indebted and unable to pay that debt. If the bank is not in a position to repay the loan then according to the special law those who deposited money in the bank will not have any right to the money of the bank. All things considered, this is the time to invest in Bitcoin instead of keeping money in the bank.
What makes it worst is that money in the bank cannot be said to be investments. Except you keep that money in a fixed/time deposit account, in this case, you can't touch it or use it until the end of the period agreed with the bank. In some cases, if you want to breach the agreement, you will do so at a discount to the bank.
It's not so with bitcoin. With bitcoin, you have an investment and at the same time, you have a currency. You can leave your bitcoin in your wallet and there's a probability that it will grow more than it was last month. There's also a probability that it will decrease, but isn't that the whole idea of an investment?
There's also the fact that your money will lose its value over time in the bank. In countries like mine where the local currency keeps depreciating, if you leave your money in the bank for a whole year, inflation must have eaten deep into the economy. If you were saving the money to use for a particular project, the money you get at the end of the year might not be able to afford that project any longer.
