Interesting!

As far as I can see, you are actually discouraging people to place bets as results will only be known (on average), every ten minutes.

I also see that you have a "block time" on the top right corner which is (I guess), your local time (GMT+8). I guess you are based (or from) China. Possible to adjust the time to something appropriate to the player, or at least (I think blockchain uses GMT)
