Coinbase is a specialized cryptocurrency-focused platform that allows you to trade digital currencies directly, including Bitcoin, Ethereum, Litecoin and Bitcoin cash. In total, you’ll have access to more than three dozen cryptocurrencies. You’ll also be able to store your coins in a vault with time-delayed withdrawals for additional protection. The exchange’s commission structure is steep. It charges a spread markup of about 0.5 percent and adds a transaction fee depending on the size of the transaction and the funding source.
