Banks are more convenient for all individuals trying to keep their wealth under control and many prefer to use cash. But I prefer crypto to bank to keep my wealth. Investing bitcoins in crypto will increase in value over time and double your profits. Banks have very low profit margins and take a lot of time to withdraw money. Also the continuous inflationary pressure of banks and lack of confidence among depositors are also responsible for this.
When you use bank to hodl your money, you have nothing to worry about the money because if anything happen to the bank you save your money, they will be hodl responsible for your money and they will pay you back your money.
But if you prefer hodling your BTC or crypto in your wallet, you will be more happy than someone that saved his money in the bank because if the price of BTC is pumping in the market, it will make your BTC accumulating.
Since many people know that bank are the full control of someone money in the bank, they don't save big money in the bank because they will not gain anything which is the reason they will use big money to buy BTC and save small money in the bank in case any emergency.
