Bank and crypto serve different purpose. If its for safekeeping, then go to the bank and deposit your money as it is insured as well on a certain limit. Don't go beyond that limit. The problem is, inflation will beat the bank interest to the ground. On the other hand, if you want investment, then cryptocurrency is one of the place to put your money, one of high risk place to be exact. You may earn a lot, a little or even lose all your investment. It's all up to you anyway. Cheers.
