I make it a point to NEVER put more than 5% of my money into a single penny stock. Not U, pamzion, but I'm sure there are some here who don't follow that rule. I've got lots of penny stocks - some I flip and some I invest in. MDNT has been a bad investment thus far because Manu decided to equity finance his vision on the backs of shareholders. I hope for the shareholders sake he succeeds, of course. But we all know, now, it's gonna take much longer than we thought if he does.
