You see, in the past a scam would never be profitable as it would have never gain traction and support of the community.
the value of a coin does not come from its mining. the value comes from its usage.
I would like to see more of such non-mineable coins... compared with pre-mining coins I would trust non-minable coins a little bit more. But ofc cannot be generalized, tho. It just gives somehow a plus feeling when checking a coin... duno, maybe just to me :-))) And it is ofc no factor to spot a possible shitcoin tho..
