Bank can trusted but as for bitcoin is one currency that can not be trusted with the bank because they can always have their way in control of it so i really can not trust the bank over some a month of money but i trust bitcoin over all transaction of money it is fast and is very easy anywhere you can do your transaction
I think there are some banks that was never a scam most of them collapse or owner brings customers money and go. but if you use a bank have the government, I think it would be quite safe. because the government will surely be responsible
What is the difference about scamming and running off with customers money? it's the same. and you are right, only use bank that's owned by the government and honestly i'm also only using that kind of bank to make sure my money was safe. the bank can't running off with your money but if you are doing illegal things and bank caught you, your account probably will be frozen
