This is one of the most strange Jackpot Promotion I ever saw. It0s value change based on the amount you bet and can get up to 90% of the total amount. You can calculate it as WAGER*90/0.01.
If you win the Jackpot, you will receive 90% from the Jackpot amount if your bet was above or equal to 0.01 BTC (Bitcoin) or equivalent value in other supported cryptocurrencies.
If your bet was lower than this stipulated amount, you will receive only a percentage of the Jackpot amount.
