Pennies typically do not drastically rise and drop. They may make a drastic rise for a very short time then tank and never come back to that level. Most do just what this one has done multiple times with different owners throughout it's history.
Flippers buy millions of shares at .0001, pump them making all kinds of claims and sell them at maybe .0004 more or less, then wait for them to drop, buy them again and pump some more sell again and keep doing it.
The suckers whom buy the hype and hold for a big payday get left holding the bag when the stock tanks and doesn't recover, the company does a huge reverse split or goes belly up wiping out the bag holders.
That's why if you study about penny stocks, it tells you they are very volatile and extremely high risk.
