Wow, I can't believe that I missed this site for so long.
I like the fact that there is a very wide range of events that you can stake on, and also that you can trade your positions before expiry. That is definitely much better compared to traditional sportsbooks who either do offer this or charge ridiculous fees for doing so.
I do wonder though, some markets are very prone to insider play (e.g. movies). Is there any strategy to mitigate this?
