The CHIPS currency appears to be solely focused on the land based casino and poker VIP markets so it's a different thing (transforming BTC into casino chips and vice versa). I will look into this more deeply though as it might be interesting in the long term. With betterbetting I agree that any such currency might not necessarily need a cryptocurrency attached to it. However, I do not see any other existing coin or option to offer bookmaker odds without involvement of a bookmaker. The KMD idea I did not fully analyze yet either as an ETH-based online casino sounds very speculative to me.
