The MyEtherWallet wallet is very convenient because you can enter it from any device with a private key or other methods similar to it. At the same time, it is only important to clearly know the name of the site of this wallet so as not to get on the phishing sites, of which there are a lot now. Also, this wallet can be easily imported into other wallets such as Klever, Trust Wallet and others. The main thing is to securely store your private key. As a required alternative, it should be printed and stored on paper in a safe place. Technique cannot be completely trusted.
