MEW allows you to generate wallets whose private key is stored digitally, it is also possible to create a paper wallet (whose key is to be printed or copied onto a single sheet). The user is then fully responsible for the security of their keys. He can consult his portfolio and manage his sendings and receipts of cryptocurrencies. MyEtherWallet accepts Ether as well as Ethereum tokens. This portfolio therefore allows you to invest in tokens as part of an ICO (Initial Coin Offering) offering ERC20 tokens.
