Steam adding CAPTCHA in trading, it means bots will not be able to send and accept trade offers. Here is link to site, where i get this info http://4pda.ru/2015/01/12/196104/
it's on Russian, but online translators still exist =)
So, what am about?
If that is true and bots will not be able to trade. Will you give my money (keys) back?

You're totally late to the party. dispenser.tf and reputable bot services have received exclusions from Steam. Bots are not affected. Only personal bots.
