As you can see, PRC is not even the highest (BD has 3x higher avg bet!) Also both BD as PRC have very close to 1% profit based on wagered, so seems very realistic to me. And it doesn't make sense to fake both wagered+positive profit since this is a very expensive joke to do on a crowd-sourced bankroll site.
Your story and "conclusion" are pretty much completely bullshit.
Better yet, I think that "number of bets" is not an interesting indicator at all and "wagered" is much more interesting, because it is a more realistic indicator of the action going on. Especially for investors. So my conclusion would be the opposite: sites like PD/BD/PRC (JD if you like CLAM) are much more interesting than Win88. Of course if you prefer the design/faucet/games there, it's okay too.
