Two reasons they bought 2 billion shares at .04:
1) there are only 700 million in the float.
If you want more than exists in the float, you got to buy restricted shares at a premium.
2) They also may not have paid all the money yet for the shares. If the investors agreed to a deal of $70-80 million for 2 billion restricted shares, they have have a delayed payment on part of it. So if it goes to .25, they can still pay for the rest of their shares at .04. It's like an Option, lock in price now, pay later. Possibly.
