The market makers are in control at the moment. If they can catch a weak sister at 8 they will sell later at 12. Try it. You won't be able to buy at 8. They sell between themselves to creat the market and catch those who just want to make a small gain if the bought very low like at 2 or 3 cents.
Pay attention to those that know what edig is all about. They do have a great future if you stick with them. you can play the same game but then risk missing what we are all expecting.
