I just looked at a few of your bets from previous books. At first glance it seems you aren't doing anything wrong. You just seem to be good in small markets. Would need to see some of your betting history here at coins.game to make a proper assessment.
I think it's no longer relevant. Whatever the betting history say, whether OP did or did nothing wrong, Coins.game's representative are not coming back to this forum to address the issue [hopefully they will, in the months to come, but not within this short future], this case will never be resolved here.
I just read their ANN thread. We should stay far away from these guys.
