I've never heard of that exchange ? (seems like an ad to me lol).
Anyway, these exchanges are centralized since they deal with real fiat money which is regulated by governments.
Actually I won't trust an exchange that's not legally registered. I don't know why but that's just what I feel is right.
If you can explain why the one you specified is better than the popular ones now, it'd be great.
You should check the site, they said it's safe to trade in decentralized exchange and it's cheaper.
Actually I trade their my tokens with ETH and it went smooth and was able to cash out my money from MEW to bittrex then to my local exchange wallet.
