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.
Yawn. Still doesnt matter, of course they can dump for free, but the pumping part is not done with XPY, you cant buy XPY with XPY, you need fiat or bitcoins to pump. So the question remains open if they are getting more fiat/btc out than they are pumping in, or if you prefer, more than they would if they just dumped their XPY stash.
You just assume this to be the case, but it requires the "idiots" to keep pouring in fresh money (not XPY) and its not at all obvious if that is happening, for sure the price doesnt tell you that.
Look at the 15m chart from midnight this morning. at midnight, 8700 coins dump the price from .00242 to to .002251, then at 12:30, on volume of a whopping 30 coins in the last half hour, the price is back at .00243. It takes very little money at all to pump the price back up, and who knows how much of it is Josh's.
