On this marketplace, you can buy lots of digital gaming goods. Mostly they are game keys, which allow you to activate licenses for downloaded games. Also, gamers trade their in-game items on g2play – skins from CS:GO, cases with a random drop.
After the registration on g2 play with an email address, you can open here your own shop and sell digital goods. The process is similar to other marketplaces. For selling skins, take them from your Steam inventory and create an advertisement. The process with g2games is similar – you can sell games-gifts for different gaming platforms.
To add funds to your account or to withdraw them, use one of the proposed payment systems. G2p conducts giveaways and proposes an affiliative program – attract new users and get commissions from their purchases.
The site g2play.net is rather a marketplace of game keys than of CS:GO skins. It has a small choice of these virtual items, and it may be difficult to find buyers for your skins here. The platform is available only in English.
