im not shure, i think that maybe some of them starts with good intents, but the problem is that some of them are not 100% minnig.
im talking about the "minning hardware".
some people start thinking that can create a "minning site"without a "minning software".
so, some of them want start investing the coins or even betting the coins with the naive idea that this bring them some profit, but eventually this collapse and they have to run, not with the winnings but with they loosses
; P
is a true story
