I can tell you right off the bat, that based on the lack of information on your website or the lack of key identifying/jurisdictional information in your ToS that you do not comply with any US-based regulations regarding money transmission services, nor with any of the European regulations with which I am familiar.
Importantly, despite claiming to be an automated platform for trading on other exchanges, your service will hold funds. This is the very definition of a money transmitter, and also makes you a financial institution under many countries' financial institution laws. As you appear to be SF-based, you're in violation of at least 2 major financial regulatory schemes--not including any state regulations.
Your website is tripping way too many red flags. You need to get these problems addressed ASAP. Bitcoin is not an excuse for amateur hour.
We comply with all regulations. This is not an anonymous site. When you are invited to trade, you will be subjected to full KYC.
Having built 4 payments platforms before, I can tell you that regulation is never easy but very necessary.
