Players at EtherCrash can bet on the house (i.e. become investors), and their bet is added to the bankroll such that they win when the house wins and they lose when the house loses. The bankroll itself is the pool of money that the house uses to pay out winners that bet using the EtherCrash multiplier. The max profit that players can win from a round of the game is determined by the size of the bankroll. The larger the bankroll, the more players can win. Each player can only win 0.75 % of the bankroll per round. Each round can only win 1.125 % of the bankroll. Every time a player makes a bet, 25 % of the 1 % house edge is awarded to the house as commission. The rest of the house edge is awarded to bankrollers. Every time you bet on the house, 2 % of your bet is paid out to the other investors according to their stake in the bankroll. Put another way, every time somebody else bets on the house, you are awarded a portion of their 2 % dilution fee. For example, if you bet 1 ETH on the house, then 2 % (0.02 ETH) of your house bet is spread out among the other bankrollers, and the remaining 0.98 ETH is added to your stake. To capitalize on the dilution fee system, you will want to bet as much as you can on the house as early as possible. As you maximize your stake, you maximize your claim on future dilution fees.
