I would rather to choose MEW wallet because this is only the wallet address that i mostly used when i join in the bounty campaign hunting and its only a wallet that contains an ERC-20, unlike the Mycrypto this is my first time to heard this kind of wallet and i've never been used it,in any kind of bounty campaign or other kind of trading investment in the trading site's and maybe this mycrypto wallet address is not available and not suited for different kind of bounty campaign.
