any sites out and around that are popular?
Im looking to do micro betting on outcomes we can deem are guaranteed fair and not relying on knowing how to verify provably fair.
I am not finding any sire as per all of your criteria. If you are very much concerned about player vs player model, I guess you have the option of betting with your friends in real time. When you are preferring dealing in micro betting, I guess you can go for betting within your friends. Then there will be no need of any fairness proving system too...
I never tried this type of betting in online. PVP betting is only possible in offline as you told we could play this betting with our friends. Some people said some sites allowed to play this betting in online, but I don't now how that process will work. Better play with your friends you will get more fun, and also there is no cheating in that betting.
