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.
I don't really follow the campaign held by BETKIN and I also don't really know the manager who handles the BETKIN signature campaign here
my suggestion for BETKIN developers is to be more careful in running the signature campaign here, because the short-term effect will not be felt to have a big impact on the BETKIN site, you have to run marketing in the long term.
