A deposit in a commercial bank is a commitment from the commercial bank to you...
How confident are you in this commercial bank? How confident are you that this commercial bank will not go bankrupt? Do you have a backup plan if such bankruptcy occurs? Are you satisfied with the amount of interest accrued on the deposit? Does this interest compensate for the inflation rate?
Answering all these questions will help you decide whether you need to keep your money in a commercial bank or not.
I agree that real money is money that you can control yourself without relying on a third party. However, finance is more than bitcoin, gold bars and cash. using all the opportunities that the financial system provides you can achieve a high level of wealth. at the same time, you need to adequately assess the existing risks and effectively use the opportunities provided.
That's the question isn't it? How confident about the commercial bank are you? And how confident are you with Binance? If you are confident enough with binance, then it is not even a question, you can keep your bitcoins there, even though many people say you shouldn't keep your money at banks. Whereas, when you think about it, too many people keep their money in those commercial banks, in tune of trillions of dollars. Banks are literally the worst thing that ever happened to the world, without banks, we could definitely figure out a way to live.
In fact, we could just have "vaults" type of companies, companies where you just put your money in, and pay them to keep it safe, that's it, nothing more, so you do not have to carry billions with you if you are rich, you still have your debit card, just not like a bank, no credit lines, no loans, and nothing more, just a place where people who have money put it in, that's it, nothing more. I hate banks, and will keep on hating them, because they never gave me a reason not to hate them.
I have a great deal of mistrust towards commercial banks. After all, they are very aggressive in promoting credit services and voluntary pension insurance services.
In addition, in my country it is impossible to prohibit obtaining a loan from commercial banks (by submitting a corresponding application in writing). And this gives a potential opportunity for fraudsters to obtain loans on behalf of honest citizens (without their consent). I hate loans.
However, commercial banks are also sometimes useful. Currently, interest rates on deposits in my country are very high (about 24 percent per annum). This makes deposits in commercial banks a good investment.
In addition, every resident of the country must have an official legal income (and not just income denominated in cryptocurrencies). Interest on deposits is just such income - after all, taxes are officially paid on them.
You can withdraw money from a deposit and buy yourself an apartment. This will not work with cryptocurrency, since it is not officially legalized.
