Re: Overview of Bitcointalk Signature-Ad Campaigns [Last update: 15-Feb-2018]
This is a very interesting thread, worth bookmarking. However, the options listed are not so interesting. And MatrixCoin is listed as available but it is already not accepting new members.
Of course, as far as you know this thread isn't updated real-time, the thread is being updated base on user's report on this thread or base on the one who wants to help this thread to be updated. And there's no MatrixCoin listed on the OP or even the updated lists, so dunno if where do you get that info
