It seems that myetherwallet is the first wallet newbies usually come across. It was my first too but it easily exposes newbies to phishing risks. I suggest our newbies get more acquainted to mobile wallets such as eidoo, imtoken, enjin, trust wallet and so on
One of the best wallet for Ethereum, and newbies should know that they have different options to store their keys, such as private keys, KEYstore file, and so on. From which, they can access and recover their wallets anytime they want. Backup of those information should be kept as safely as possible to avoid loss of money they stored in their Myetherwallets.
