Assume that Josh is dumping 100% of what he can daily. What could he possibly be making at the current price and volume? The coinstand pump was the last gasp, we won't see another.
Assuming he has 15 PCs he would be getting ~5k XPY per day, or 600-700 USD. Not too bad I guess. But miaviator keeps saying that "snake" Vadala stole the PCs so there's that.
Why does it even matter if Josh has control over those 15 PCs or one of his disciples? The bottom point is that more than 10% of money supply are in the hands of a single person who didn't incur much cost (if any) in obtaining them. The same applies for the rest of PCs that are in the hands of Foundation and Team XPY
