Most of the guys I know get in at the ask with pinks and OTC. When all I see is action at the bid, I highly suspect dumping. If all you do is wait for the bid you don't create momentum and a penny stock needs hits at the ask. I also sell at the ask, not the bid *ever*, even when taking a loss overall. You want an uptrend, you have to help create it. MM's play the spread, if the balance of action is on the bid they lower the tick. Not like I'm an expert or anything but that's what I've learned from people more knowledgeable than me.
