The reason given seems to be related to participants not providing TRX addresses because the campaign manager has decided to redirect payments from Bitcoin addresses to TRX addresses.
The worst part is that, some participants had been marked paid and some are still left with no payment even after submitting TRX address, some are still yet to submit their address don't know if the manager has notified the them do repaste new address. This is the worst unprofessional campaign manager so far in the forum, he is joking with his reputation and I wonder how he could be able to manage campaign properly next time.
He can't manage a campaign properly, he can collaborate with a professional manager to support him. This how it does, either he discuss with the manager to work with him as a participant in the campaign and he takes lectures from the him or he hand over the campaign to the manager and became a participant in the campaign and moderate the campaign. These are some ways to become a professional manager in the forum. When I heard that he has not paid his participants till now, I was surprised about the news. This can damage his reputation in the forum.
