Why would you look for the buyers if you can just make money on cs go by selling skins on platforms that don't require other people? There are platforms with instant payouts, so I'm pretty sure that it's a way better option for you than waiting for a buyer. You can also get scammed that way, so it's also not really safe.
You know, I prefer buying skins for cs on special sites, because it always seems to me the safest solution when it comes to money. Plus, it's nice to buy skins like https://dmarket.com/csgo-skins/product-card/m9-bayonet-doppler. I've been wanting to buy the Doppler skin for a very long time because it looks really cool while playing.
