That doesnt matter. If you are the only trader you can pump to the moon but dumping still wont make you a nickel more than you began with. You can only make a profit if you can dump on to other people's bids, and if no fresh capital is brought to the market by others, you dont profit from pump and dump. Hence its not obvious at all if its working.
they aren't using their money to pump, that's the beauty of this scam. They say they will announce something, idiots pump up the price, GAW dumps. Rinse, repeat. It's been going on for months.
In a traditional pump and dump you need to spend some money to pump up the price and get the coins to dump, but they have coins to dump and idiots to raise the price for them.
