We're always here to help, and we're never giving away ETH.
Way back to 2018, MyCrypto was nothing more than a fork of the existing MyEtherWallet, many things had been changed since the mentioned time. Both wallets are well-known wallets for storing ETH and ERC20 tokens. I prefer to use the MyCrypto desktop app after the latest updates on Myetherwallet site, there is no option to create a new temporary ETH wallet with the private key. The whole process can go up to 5-minute per single ETH address because of verifying seed or mnemonic phrase. The Mycrypto app made it simple and the KISS(keep it simple stupid) rule is my first criteria for saving time. Just using a random password without downloading the JSON file, it is simply easy to copy and save the private key of the new ETH wallet address.
