I first came to Prediction Markets in connection with the Blockchain after reading about STOX and registering promptly. However, the realization of their idea bored me so much that I don't use it at all anymore. With STOX, there is also the fact that the actual functionality is different from normal betting. It works rather as a kind of database for prediction and remunerates the users according to ranking in monthly tournaments.
In principle, however, I also think that this market segment will become very interesting in combination with decentralized structures. So I'll be surprised how WaykiChain deals with the topic in the long run and whether the project will bring about what you're talking about in your blog.
