I defend my pockets to scammers in myetherwallet because there in etherwallet extra we want before you sign up and that i defend my wallet to scammers is the way i understand and i don't deliver my pockets password or any want to register and this is my opinion.
Hackers are attacking the very cryptocurrency market so investors need a way to protect their assets. For the ERC20 token on the MEW wallet I usually use Metamash and mycrypto to hold and exchange, for other coins like BTC, altcoin it is safest to use a wallet or hardware on the main website of that coin.
