What is cryptotalk.org
Cryptotalk is another forum like bitcointalk. I see cryptotalk signature first on yahoo62278's profile. Recently Yobit announced that next yobit signature campaign run on cryptotalk.
is it on everyone's profile
I think cryptotalk contact some bitcointalk members by pm and asking for add signature. Like signature bounty. If any trust person pm you. obviously you believed that.
Is it like bitcointalk and does it also have campaigns?
Yes like bitcointalk. Bitcoitalk is forum, cryptotalk also forum. Already Yoda airdrop was launched. And participant got profit from that. After someday yobit launch another signature bounty on cryptotalk. But, now cryptotalk bounty/airdrops place status not configured. Because, so much inexperience members here.
