Yeah, this is a major problem with OTC exchanges. If your fees aren't large enough to cover possible price fluctuations, you're going to have issues. And Bitcoin can be very, very volatile sometimes.
Very true but i always wonder how exchanges like Coins.ph or coinjar manage this issue who have almost instant exchange time as soon as the order is put in.
I wouldnt say coinbase because they usually make people wait 4 days for their coin.
Duke!
There are instances where Circle returned money because of price jump after the order was locked. Just have it written in your ToS, that u can do so. As long as you are returning money/coin without any commission no one can charge you.
