ItBit is continuously working to refine how crypto is traded and offers exchange services, over-the-counter trade, Escrow and Custody services. itBit also plans on expanding introducing new features like collateral services, where you can offer digital assets as collateral when trading other assets.

Before, you could only trade BTC but now they have added Ethereum, Litecoin, Bitcoin Cash, and Stellar Lumen. Itbit is one of the biggest exchanges, and definitely worth looking into further.

Hope this helps!
