Basically, banks only manage money deposited by customers with a written agreement. Automatically, when a customer needs it for a purpose, it must be provided and you cannot say no, even if the customer wants their money withdrawn in large amounts and requires a series of requirements to be completed.
If you think about it, the system for saving money in the bank is too complicated even though the money we save in the bank is guaranteed. But because the process when I want to make a withdrawal is too complicated, I dare to conclude that there is no freedom to save money in the bank. Our money but not ours. We must completely prove all the data when we want to retrieve it.
I really agree with what you say, banks only manage money saved by customers and when there are other customers who want to apply for a loan at the bank they will give them money that other customers have saved at that bank and if customers who save money they want to make a withdrawal must prepare files that comply with the requirements provided by the bank.
For some people who understand this, of course they will not save large amounts of their money in the bank, but they will use the money they have for various businesses or real assets and this will also be more profitable for them.
For someone like me, I can’t save large amount of money in the bank (if I had large amount

). Because I already know how the bank operates and it’s impossible to unlearn it for me. So if I were to deposit a large amount, I’ll feel like I’m just giving out my money for nothing. Because the interest is almost nothing. So, maybe I’d rather hold it in crypto, and deposit a smaller amount in the bank. Or even use the money to open a business because it will give better returns than the bank.
