As we said before, the signature campaign is on a short break, and we will relaunch it soon.
Dont you have plan to pay btc?? Because i think btc payments are more attractive to people so you can gather more participants aswell as you can move this topic to service section, POST coin really is in bad shape now and its low value thats why the participants here will surely jump to another campaign if they can see better paying ones.
Edit: goodluck to relaunch hope to see better payments result.
