This IOU trading is spamming everywhere, it would be better to avoid this. The most common things about IOU is the price will always be dumped when the real one comes. Though sometimes its quite affecting the price at the launch.
many people are not understand that what's in the traded in liqui just IOU, and prices now in liqui does not describe the actual price at the time the Antshares will start in traded, it is better not to participate in the trade of IOU because it's just like fake traded
