Interesting that a whole economy is based on fake supply constraint. Or is making butterfly knife really hard? It seems like NFT before NFT.
it's not a fake supply CSGO knifes actually currency run by shadow banks providing RMB USD convertion. Google for "挂刀"
> "Selling Knives" (挂刀) refers to the technique of buying in-game items from 3rd-party (Chinese) trading sites like NetEase BUFF, C5, IGXE, and UUYP, and then selling them on the Steam Market to obtain a discounted Steam Wallet balance by capitalizing on price differences.
I'm surprised the price difference did not disappear if people make that trade.
