The problem is that 90% of altcoins are concentrating on making paid campaigns on their own altcoins that most of the time these same altcoins are worthless, if the owners of the altcoins concentrate on doing signature campaigns paid in bitcoin then they would have bigger exposure of your product, because many people would participate in the signature campaign, participate in twitter campaign, facebook and yotube.
