Ride the waves if pink or otcbb or amex or nyse, trick is, doing the buy in point right when riding the waves. Enron was hardly a pinksheet stock...nothing ventured nothing gained :O)
I do agree with you though on paid advertisements one must read these things with a jaundice eye. But, its not at all a pinksheet phenomena...its also an otcbb, amex, nyse...its all relative imo.
OBTW....Low entry points can be quit rewarding no matter what stock exchange one has decided to go with.
GLTU!
