# Cost & Benefit

<mark style="color:green;">If we put in the cost and the quantity factor of sales, we will get the following cost-and-benefit relationship:</mark>&#x20;

_<mark style="color:purple;">Single team (40,000 in total)</mark>_

_Sell 5000 tickets, the average price of options is 3.428 USDC, the highest price is 3.918, and the theoretically recoverable is 3.428\*2=6.856 USDC after winning the championship (other teams also sell the same amount)_&#x20;

_Sell 10,000 pieces, the average price of Option is 4 USDC, the highest price is 5.33, and you can theoretically recover 42= 8 USDC_&#x20;

_Sell 15,000 tickets, the average price of Option is 4.8 USDC, the highest price is 7.68, and you can theoretically recover 4.8\*2= 9.6 USDC after winning the championship_

_Sell 20,000 pieces, the average price of Option is 6 USDC, the highest price is 12, and you can theoretically recover 6\*2= 12 USDC after winning the championship_

_Sell 25,000 copies, the average price of Option is 8 USDC, the highest price is 21.33, and you can theoretically recover 8\*2= 16 USDC after winning the championship_

_Sell 30,000 copies, the average price of Option is 12 USDC, the highest price is 48, and after winning the championship, you can theoretically recover 12\*2= 24 USDC_

If all teams sell all 20,000 options (a total of 40,000 tickets), and team A wins the championship, the final return is double the average price of 8 USDC sold 20,000 tickets, that is 16 USDC. The first buyers who spend 3 USDC to buy can get 4 times more income, and the later buyers, despite the decline in income, can still get quite considerable income.&#x20;

**In this model, we will find that users who participate early are the most profitable at every stage.**
