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.
