When I was looking for rare skins like the AK-47 Bloodsport, I wanted something reliable too. It’s always a pain sifting through all the shady sites. If you’re looking for something trustworthy, I’d suggest looking at https://dmarket.com/csgo-skins/product-card/ak-47-bloodsport . It’s a platform I’ve used to grab skins before, and I’ve never had an issue. The transactions are secure, and they have a good variety of skins, including the AK-47 Bloodsport you’re after. I think you’ll be happy with what you find there.
