What is cryptotalk.org and why is it on everyone's profile? Is it like bitcointalk and does it also have campaigns?
Cryptotalk is a forum site own by yobit, before people are wearing that signature but the campaign has already ended, so now people are wearing yobit signature while the personal text are still the same. AFAIK, the campaign are still running in their own website, so if anyone wants to join, they should check the website. They run a campaign here to promote the website actually.
