I think X-Cash can soon have bitcointalk signature campaign. I think we are near bottom market and starting the campaign now can make it an awesome airdrop.
The Xcash team confirmed weeks ago that they will open the campaign soon.
No one knows when they open it, but soon.
It was first announce last December 2017 and they made a follow up announcement again earlier this week. We can speculate that the signature campaign will go live this 1st week of February 2109 or Before that time

Lets just wait for further announcement.
