Yes it is a great platform for bets. They seem to be creating the ability to do everything Ethereum can do except it is attached to the bitcoin blockchain which costs extra BTC and causes a lot of extra data on the blockchain. Counterparty seems to be far ahead of Ethereum in creating this environment, but I think if Ethereum can produce what they are promising then that will be the better platform.

By the way on BetXCP where you buy XCP from Vennd.io they sent my bitcoin back and did not send XCP, so I guess that service is not working at the moment. I guess they are not getting much action and are slacking of on the XCP betting thing. At least they took the time to send my BTC back minus a small tx fee.
