From what I gather. It allows for unlimited brimstone from one legendary.
As to how to do it? I haven't got a clue.

Even if this was true...how the hell do you turn over 20 mil? in brimstones?

I have 1x here for 20 million

in that case..

23 @ 100m each you'll get your money back selling 1billion brimstones

ISO 1 burger VS 20m IGG LMK

mabe have have buy all the fuking hamberger at the ah for cheap ALL of them and then put them all at couples of millions and made a prety red post on jsp so people look at ah saw the cheap hamburger at 2m ,,,

This is probably the case to be honest.
Hype something up.
Inflate the prices.
Resell.

Edit:
Hence the legacy. Since there's only a bit of supply. Could easily be manipulated. Unlike the non legacy burgers.
