I am using this wallet, but I find it safe to store the tokens I have earned and accumulated, even if I do not like it. Over time, I have read some security vulnerabilities, ie the existence of counterfeit sites, and I have spent more effort to be more careful. Erc is a 20-based system. For the transfer of tokens, a certain amount of etherium must be kept in the account. Although it is complicated to make transactions for some, I think it is a wallet that can be learned and used by research.
A popular and popular wallet all over the world
But as I mentioned, there are too many fake sites and these sites should be careful
