Hello,
I'm selling a gambling website with the domain, the server, the twitter account (3k followers) and a brief training to show you how everything works.
The website is based on angular5 - Nodejs (express, mongoose). The current games are Jackpot, Roulette, Dice and Crash. It has a nice admin panel where you can customize a lot of things.
It is based on csgo items and is not impacted by the valve changes on csgo items as the items are only used through the deposit/withdraw panel. You can easily switch the game to pubg, rust, h1z1 and any games steam has with an inventory function.
I'm also developer so if you need some changes, that's also something possible.
DM me for more details !
