MyEtherWallet is not a wallet. I suggest to everyone and each of you READ what is written in slides when you open either MEW or Mycrypto interface. Everything is written there. MEW is an interface, it is not the wallet, bank or anything like that.

Both MEW and Mycrypto is safe enough for me. I don't usually use json and I never use private key, I use Metamask connected to the Mycrypto for my daily use and Trezor with Mycrypto for the stagger solution.
