My favorite exchange at the moment is Tap . Many aspects appealed to me and a few of them are: - You can view your portfolio whenever and wherever you are on their simple and functional cold storage e-wallet. - You can send and receive crypto and fiat currencies through their app. - They have a card that lets you spend your assets on day to day spending habits. - They make trading less risky with a smart-trading system that automatically selects the best price for your trade-in seconds which guarantees you the best price.
