This is a very very short tutorial on where you can start trading Cryptocurrencies. These sites are to trade one type of cryptocurrency to another type of cryptocurrency. For example, convert your Bitcoin into Ripple. Some of these sites may do more than Cryptocurreny - Cryptocurrency converstion, but the primary use is for exchanging one type of Cryptocurrency to another.
Bittrex - Requires ID Verification
Binance
