First, you should invest in some or more FUN tokens because they are very cheap currently, hence you would get additional premium membership perks for a very small price, that is to say a cashback on all your bets, an increase of your daily interest earnings and some daily free WOF spins(currently suspended for most people though). Then you could try to play your bonus during a 6hours flash promotion, in order to get the rewards of the flash promotion on top of those of your bonus. You can also bet on easy or (almost) sure victories of some soccer teams on the sportsbooks page, you will get RP points and lottery tickets from all your bets (4 free lottery ticket, 5 reward points for every 0.00000500 BTC and 3 free golden ticket for every 0.00500000 BTC wagered)
