There can be multiple winners of the lotto jackpot. The 1st winner receives 50% of the total pot. The 2nd winner receives 25%, the 3rd receives 12.5% and so on until the jackpot is less than the price of 1 ticket (the minimum win amount). This ensures that every ticket has a higher chance of winning something.
If you have won the lottery, you now have a choice to either hold your DELO to earn passively via frictionless yield, stake your DELO to earn a % of every ticket sale, or sell your DELO if you choose not to earn additional rewards.
