I just finished some PTS purchases on coingrounds. It was nice that only one BTC confirmation was required before I could start to trade. There were fees on each trade. The FAQ says it is a 1% "optional" fee, but I didn't notice a way to avoid it. There is a checkbox to skip the 2% withdrawal fee, but when deselected there are large fees taken from the withdrawal anyway. I appreciate the exchange, but the fees seemed high. There is also a bug in the matching engine. I'd placed a buy order for several hundred PTS. Only about 100 filled and there were probably 500 more shares below my offer in the market. Even after a refresh you could see my order with a higher offer than asking prices. I canceled my order and bid again to pick a couple hunderd more up. I had to cancel and repeat to pick up the remainder. My original order should have been a complete fill. Someone else noticed the crossed orders too and commented in the chat box. Large orders do not match properly. Much better than spreadsheet or escrow purchases in a forum, but there are a few bugs to work out.
