CSGO Case Opening Sites and their beginning
It has all began with Counter-Strike: Global Offensive. CSGO Case Opening sites were one of the most popular gambling sites within the Counter-Strike community, where you could get new CSGO Skins for your inventory.
It has all started back in 2013, when Valve introduced virtual goods (known as Skins) to CS:GO, after successfully implementing them in their other games (Dota2 and Team Fortress). Players could obtain them for free while playing the game (as a result of a random skin drop), watching matches, unboxing cases with keys bought in the in-game store or buying Skins on Steam Marketplace.
CSGO Skins had different value based on their rarity or other characteristics and have quickly become a sort of virtual currency and foundation of one of a kind virtual economy. Steam Marketplace and it’s limitations could not meet the demand of this booming economy and therefore created a space for third-party sites offering CSGO Skin Trading, Case Opening and other products highly desired.
Even though third-party sites were one of the biggest contributors to the Counter-Strike's popularity, Valve has decided to send cease and desist letters to all sites, saying that they violate their TOS. Some sites have ceased their operation, whereas other continued to offer their services (trading, gambling, match betting) to the community. Valve was fighting remaining sites by banning their trade bots but it was a kind of a cat-and-mouse game because these CSGO Case Opening sites kept on creating new bots each time old ones got banned.
Finally, in March 2018 Valve has decided to ban Skins trading (or make it a lot harder by introducing 7-day long cool down period).
As a result many of the case opening websites had to shutdown or change the way they were operating. Some of the have decided to keep going and allow players to open CSGO Cases like before, but the skins from the drop were converted to crypto if someone decided to withdraw his winnings.
