I just tried a couple of bets. I bet 1 satoshi at 2x each time. Won one and lost one. The 'my bets' list is weird:



What is the 'return' column meant to show? If it is the profit per bet, it is wrong. My profits were +1 and -1 satoshi.
If it is the payout per bet, it is also wrong. My payouts were 0 and 2 satoshis.

And that's after my first two bets. Who knows what other weirdness lurks.

Edit: I tried 2 more bets, thinking the 2 satoshis might be a rounding error. This time I bet 10 and 20 satoshis. The loss of 10 shows as -10, and the win of 20 shows as +40. It appears you are showing "profit" for losses and "payout' when for wins:



As for "#1 site by growth", I think you're optimizing the wrong thing. Achieving 400 million bets in 4 months is easy when you pay people to bet. Almost all of those 400 million bets were made with your own money, via the faucet, and contribute nothing to your bottom line. Maybe try comparing your site to other sites in terms of amount wagered, size of bankroll, site profit, or any other meaningful statistic.
