Banks have the same policy,rules and regulations.Banks can be trusted in savings money.They also have secrecy law which prohibits banks to disclosed any information of the client's account.All money deposited are insured too.that no matter happens with the bank. The money is guaranteed to be given back to its clients.
Haha, in my country, the government said saving money in bank is also an investment type, because you are lending to the banks with low interest rates, therefore, the risk of banking still alive. What do you think about that? For me, this rule exists because of its nature from the beginning.
