In fact, the wallet is due to our habitual use and ease of use, if it is a matter of safety or uncertainty, it depends on the owner whether they can properly store the private key so that other people don't take it. or you can use a more reliable offline wallet.
until now I only use MEW and Blockchain, I think I can meet the needs I want, there are no plans to change it. If there is money, you will definitely buy an offline wallet.
