use loot.farm or cs.,money , lowest fee's
some this like tradeit.gg or csgoswap have like 13% fee's :D
i usually use cs.money and selling at bitskins
I´ve used bitskins in the past to sell and buy a couple of skins without any problems. For pure trading? I have no clue and with the amount of scammers there are, it´s not something I would want to do...
ive always just used cs.money when i got bored of skins and accepted the cash loss in favor of easy usability
