It's part of the game that those in the know play, IMO. They are slowing transferring shares into the hands of those that know it is going up bigtime. If you can wait them out, then you get to share in the booty. If you can't, and sell, then you get to shake your head wondering how you could have been so stupid. You can say "If I had only held, I could have made 100%-1000% on my money in one year!!!-Oh well, I made 3% on my CD".
But then again, you could loose it all. That is the life of micro stocks. I have done that a few times also. You just never know what the future holds, but the odds of you winning here are much greater than at the craps table.
