Yobit has been running a lot of ads on coinmarketcap but they still haven't been paying people for their signature campaign.
AFAIK, payment was done first before ads will be placed on Coinmarketcap. On the other hand, not the case in the signature campaign so they can do
sh*t about payments.
Even back when they are active in sig campaign here, that
"blue button" of theirs is not always working. There's a user here who take the risks of staying in Yobit sig camp even not receiving payment for several months or I think that was over a year*. I don't know if that user got paid eventually.
If they'd just fix their issuers and hire someone bounty manager here, they still can advertise in the forum and it could possibly earn the trust of the users. Yobit has been one of the surviving exchange since time. I can still see users wearing signatures of yobit but pretty sure they are not paid as well. I have chat yobiit support about it they were saying they are paying but checking my account the btc can't be send to my wallet.
Nothing will change to their overall status even they hired a reputable bounty manager here. It will not change the fact of how unprofessional they are in general.
And prior to that, I doubt a reputable bounty manager here will accept the work.
