When you want to create an online crypto wallet, some of them will ask about your personal information (such as name, address, phone number, etc) to verify your account. If you don't verify your account, they limit how much money you can send or receive in a month or a year. What is the point of this verification? I think this is a big contrast with crypto anonymity. Everyone joins crypto community to trade or transfer money without revealing his/her personal information. This is the real difference between bank accounts and crypto wallets. People do not use cryptocurrency to be controlled by a third party. They use it for independence.
So, why should people give their personal info to some online wallets? What do they want to do with people's information?
