I've never used it before and I'm not interested in using it, it's too haphazard.

The easy one is why take the complicated, anyway I also rarely use Coinmarketcap trading services, only occasionally.

Let me tell you for now I use a trading service (BitUniverse-Crypto), this is the most favorite trading site for me, every day I explore it.
If you are interested try installing the BitUniverse application, I'm sure you will enjoy it.
