Penny stocks and OTC Pink Sheets are dangerous as all get out.... But, if you do decide to go that rout, never (and I mean never) hold overnight.
If you are looking for INVESTING advice, though, I would turn to CNN Money, CNBC.com, Stocktwits.com and Estimize.com
On Stocktwits,just look up the ticker and get the consensus. Also, before you blindly get into the markets, make sure to watch CNBC at least an hour a day. Learn Buffets ways, like someone said earlier.
