Let me assume the question is what is called the predictions market in our wonderful world of crypto gambling. Mayweather hyped up the Stox ICO recently, based on Bancor. I don't follow that but I assume the hype should at least lead to some working prototype.

I do very much like Byteball, and you can already try it out within the wallet with a smart contract. Check out: https://medium.com/byteball/making-p2p-great-again-episode-iii-prediction-markets-f40d49c0abab

If you want, you can try this out with me, I'm always keen on Liverpool matches (football) - just drop me a PM and we can work out a bit of fun with GBYTE.
