CSGO Gambling site

Making a CSGO Crash/Upgrade site. Must be good with steam api. Have a very good understanding of how i would like it* //////////////////////////////////////////////////////////////////////////////////// Upgrade: Users deposit skins to our bot and then can upgrade it to another "skin" with a % chance for ex a $75 skin would have a 65% chance of getting a $100 skin (+10% house adv) and if they upgrade succuessfully they get the skin. If they dont they lose it. Crash: Users deposit skins to our bot and can put it in once it is clicked in crash it is confirmed for the next round. The % increased is shown by a graph. If it "Crashes" before they cashout they lose the skin. If they do theyll get the ammount shown when cashed out for ex a $1 skin at x1.56 will go to a 1.56 skin. Chat: have a chat system with the users steam name on it Level/Affilate system: users can level up by depositing skins ($.10 = 1xp) 500 xp = lvl 1 Once level one they will have perks such as daily wheel and more. For affilates users can create a code and get friends to use it. Their friends get $.50 and they get $.05 per code used.
