Gotta just ignore him. Trick with penny naysayers is that they will always be right at some point, because pretty much all pinks are scams.
But for all their naysaying, one has to ask whether they make any money off the updrafts when they do happen.
Some may be affiliated with hedges and MMs that can short pinks. Those folks will pretty much always win except for the occasional squeeze mishap.
But given his adolescent ranting, I'm guessing this one is a young clown strutting his rooster feathers here because he hasn't much to strut in real life.
