Yobit and betcoin.ag(had a campaign in the past) are both negged and from what I remember they have red (*) asterisk on their campaign here, is that because they were red painted or there really is a problem on their camp.?
If I'm not mistaken, Yobit got red asterisk because there was some problems with payments - their signature campaign wallet wasn't refilled for month or two several times.
Betcoin.ag was marked with red asterisk due to scam accusations against them.
