The MyEtherWallet service allows you to manage your Ethereum portfolio (and the ETH tokens) as well as send coins from your personal wallet. The service offers support for file-based wallets and physical wallets (offer greater security against theft).
One of the best features of the service is that it has a very friendly interface which is essential in the world of cryptocurrencies where everything is so complicated and it is vital to simplify the management to avoid losses. The application also has support for physical wallets such as "Trezor" or "Nano Ledger", which we must previously connect to our computer using a USB cable.
We can also highlight the possibility of using MyEtherWallet on our computer locally and without accessing the internet to manage our wallet and sign shipments without risk to security, the signed file can be sent later to the online version of MEW to propagate the transaction.
Myetherwallet also allows you to create your own purse in a file that the web itself generates using random algorithms that calculate your private key by means of javascript.
