I am only using Myetherwallet as a default wallets in ERC20, but I have multiple address to avoid some scams in airdrops and also in bounties, we can't deny that this wallets is the most useful for the newbies in crypto.
Yes i used also myetherwallet fora longer time and so far all my tokens are still in it,.so i really trust and beleive myetherwallet im using now,.so i think whatever wallets we have as long as we keep our keys safe and make it double or put it in a note so its a better idea also.
