I've made a quick compute on Poloniex.
for around 1BTC (1.08 actually) a buyer can close all sell actions (which means around 78K Fox)
The question is to know how much this guy would win in case of resell. (in fact 3.75BTC if it's reselled at 0.00005 BTC/FOX)
edit:
I missed last lines which are obviously the most expensive.
One guy sell 152K at 0.0001 (so 15BTC)
For buying all sells it would cost 17.49BTC (for 243022 FOX)
Not the same budget!
