I wonder why anyone would even think of buying shares with a local bank or saving huge part of their money with them, when they could save for a long-term with Bitcoin and make huge returns later, Bitcoin blockchain makes it very secured and the only ways an investor is at risk is saving their asset with a wallet that could easily be penetrated by hackers or fail to safeguard their private keys.
Banks also have different categories. If you deposit money in a top level bank, there is less risk, especially from security risks, but if you deposit money in a middle class or lower level bank, there is a higher chance of losing money. So keeping your money in Bitcoin is safer than worrying about keeping it with someone else. Especially if a good wallet is selected and the security keys are well stored and Bitcoin can be held for a long time, it can give a much higher return than any bank. The opportunity to keep your own money and build great wealth there in the long term is no less than a bank. Moreover, those who can predict the future will definitely choose Bitcoin.
You are right, each bank certainly has a different system as you said and also there is very little profit that we will get from saving money in a bank but we can save some savings for emergency needs that we need in the bank and save in Bitcoin as an investment in the long term and also we will be able to make a profit from it but we must be able to take good care of the wallet key that we have.
Choosing to save your own money by investing in Bitcoin will be very good and we must be able to do it consistently in order to make a profit when it is bullish and it is very impossible to get it by saving money in the bank, it will be very detrimental when inflation occurs, the value of the money we save will decrease in value even though the money we save does not decrease.
