what is a safe wallet for storing ethereum after getting paid from ICO?
There are many purses for the Ethereum crypto currency. For example: a browser-based online wallet platform (MyEtherWallet); official local wallet from the platform creators (Mist); multicurrency wallets for PC and smartphone (Jaxx and Exodus). Also after the ICO, you can store coins on the ethereum platform on crypto exchanges (Poloniex, Bittrex, YObit).
