regular wallets for example such as Etherscan and Windows wallets,which do you think is the most secure for each campaign you participate in?
let's share a little because every Windows wallet I have ever participated in always fails to be exchanged or sold when the token is on the market exchange..
Check their security features. Any wallets will do as long as it was secured or a non-custodial.
The wallet has nothing to do with the coin's value once it reached the exchange. There's no relation to why you weren't able to get profit out of it.
