I don't really hear you.
Pink sheets are scams ,mm play with it
Otc is upgraded. Same mm play with it
Nasdaq the best market, yeah you can only play a little knock stock price down few cents
However its not true. Someone wants in at 4 dollar price ,stock is $ 7
No problem, either they short it ,or simply post lower prices , till its at 4
That is called unfair manipulation
Imo
