To be honest Banks have liabilities to other bigger banks and instutions
Banks don't own you any responsibility on what they use your money for and they are surely in business with your money.
If you own funds in bank it's not yours
Surely it is no longer yours if you have decided to take your money to your bank, it becomes there money until you demand to withdraw it .
The thing is that banks and other debit credit instutions don't expose to customers openly info about how much leverage or risk they have and liabilities what they need to pay to other financial instutions If not they must liquitate their assets.
In times like this you only want to deal with bigger banks and credit /debit instutions.
They don't have to expose their access and liability to you as an individual but they publish their annual report and share dividend with their share holders. You can find that in the public but they own you no responsibility of explaining what they used your money for. They are in business with your money definitely and if you are not cool with that then you won't keep saving in the bank.
But i feel that crypto and cash are real money the bank balance on my bank account i feel little sceptical yes banks are safe but still i need that feeling that at least some of my funds are under my own control.
Yes right . Cryptocurrency gives you that custody of your money in crypto to the exclusion of others.
