Thank you for your reply. And also all others who replied, I really appreciate you reacted.
So to start with, the idea of the project is pretty simple.
Each day a pool of all the bets made within 24 hours is drawn, so the winner gets a fixed % of the whole pool.
The rest is split between smaller prize winners, the lottery organizers and eventually blockchain fees.
The bets are made in USDT directly. There is no need to buy any tokens, or any lottery tickets.
One bet is 10 USDT. Players can place as many bets as they like to increase their chances.
The logic behind the lottery is fully coded into a smart contract - bets, random winners selection, payouts, so it is really a blockchain lottery.
I think you should know the fact that such ideas are likely to have pretty numerous cons, yet the most disadvantage of that system is its fairness issue. If you could make a logic that wouldn't be favorable or bias on certain bets or just have the winning numbers be totally random, it would now make another con which is your user's trust. And what would they found much suspicious is the ticket/bet price which is too high compared to common lotteries. If you really want audiences, making blockchain lottery is fine, but you would struggle with gaining client's trusts and finding fairness bugs in your system..
