I played a couple of bets and noticed that immediately after i place one 0.01 bet, another one is placed on top of mine, at 5-10 secs. difference.
My guess is you have a 'bot' that places bets immediately after a player bets, to always be the top player and win it all.

I know blocks can't be predicted, but this way you increase your chances exponentially.

I may be wrong, but this is my first impression.
Will play more soon.
