CSGO500 is a gambling website that was only about CSGO skins betting. After VALVE released a 7-day trade ban for CSGO skins, CSGO500 had a long break. They've worked on a workaround to allow players to deposit and withdraw skins using the Player To Player (P2P) system, which was a great success. Soon after, CSGO500 started adding new deposits and withdrawal options and became one of the biggest sites in the skins gambling industry and is now expanding on cryptocurrency and real money markets.
CSGO500 is giving a lot to their community in the form of daily bonuses, a train system, sign-up bonuses, and way more. If you haven't used the referral code on csgo500, you can use provided code to get free 500 coins (which is $0.50 worth of skins).
