I've never use mew wallet before but if it's an online wallet stay away because they can easily get hack it better to use mobile wallet that gives users their private keys or recovery seeds do not use any online wallet that operate with username and passwords also if you can afford the money it is better to buy hardware wallet there are hundred percent safe unless you reveal your private key for the hardware wallet
since 2018 have kept huge amount of ETH in my trust wallet and nothing happened to my assets so mobile wallet is a good choice too if you can keep your private keys very safe
