Exactly , you can have any strategy and by all means the 'best' strategy is subjective but even if you find the 'best' one , you can't win against house edge in the long term.
Actually, MoneyPot is special. Really special. No other site has the type of bonus like on Moneypot. I've seen bonus multipliers of up to + 0.08x your bet. Meaning, if you include the house edge, you could have a +7% house edge. But that is based on luck. If you notice how a different high roller is playing, try and grab the bonuses, and maybe you'll win yourself some good money!
+7% house edge just happens when your bet amount is tiny , if your bet amount is bigger , you only get <+2% bonus ( often is 1%)
