I was checking my trade log and apparently people are having trouble purchasing my item but especially my trading cards. about 90% of the purchases are cancelled and or reverted. I just noticed this and I would like to find a solution asap.
thanks
Solution: Due to a new Steam regulation, in order to trade Steam community items [trading card, gems, emoticons etc.], your account must own a game with trading cards support. Working games include cheap games like Bad Rats or even free games like Dead Island Epidemic.
To VIPs: You can look into your bot's inventory and find if your Steam items are tagged tradable. If necessary, you could send a game to the bot for redeem.
