You're correct in that you'll have to trust us for a few minutes when we process and perform the exchange. We acknowledge this and we are ready to earn users' trust with time.
Yeah, and that is what makes it centralized and custodial, just like other instant exchanges, the moment funds are deposited into the deposit address you provide, you have custody of the coins. I don't have a problem with instand exchanges, in fact, i believe we need more of them that are legitimate and privacy oriented, but it is good to set the records straight that they are centralized and custodial, so newbies know this before going ahead to use them.
