Whether he plans to make this money mainly through trading, or through GPUmax or though other businesses, or though a combination of things, remains to be seen.
At this point another major way would be to buy back his own devalued debt: FOO.PPPPT "bonds" are on sale at less than 50% of nominal price, and many PPT holders are selling at a discount (which will grow by the hour as the panic level rises).
I'm not into that market but wouldn't he need BTC to pull that out?
That would be an scheme to make more profit, in case he had enough coins already to pay his debt. If that's the case, props to him.
