The real thing why would people say that mining in phone is impossible, because nothing among the coins out there are not capable with it "right now". So they are right and don't make​ them wrong because they are only feeding you with true facts. The difficulty is way to high to become profitable.

So let's just wait for your ICO to come out and let it bent the fact that mining would be possible. Or let it prove itself that it is a one new gimmick or what to gain investors like you that knows nothing about mining.
