So after you have done everything, you're going to implement my design. (PSD to CSS/HTML) Script will launch like; 1- First they will give their items to our trade bots. (They'll click the deposit button and a new tab will open in their browser. That tab will be their trade link to our bot/s. They will accept the trade.) 2- The items that they gave to us will gather into our skin pool. 3- In the pool, there will be a limit for how many skins you can deposit (10) and the minimum value of skins. Also, jackpot will have countdown. (120 seconds) 4- When the countdown is finished or when 30 skins gathered into the pool, script will pick a winner using hash or something. 4.1- Winner will picked due to the value of the skins that he/she put in the jackpot over total value of the jackpot. For example if total values of skins in pool is $100 and he/she put $60, the possibility of his/her win is 60%. 4.2-I will get a small percentage of the total value of the pool. (4%)
