It is not about not trusting banks. Its about choosing the best bank available in your area who has the "lesser evil". Each banks has it's own pros and cons. You need to weigh down the differences and stick to the ones that will cater to your banking needs.
I agree. There are many banks that are extremely good. But in my coutry, banks are not very good. THey are truly scammer. Actually, they are not really scammer but their agents are scammer. Banks can not control those people and they refuse to take responsibility of their agents
