“This has the potential to do a Lehman type blow up”
Really? What evidence do you have for that assertion? What bubble exists, where are the systemic risks linked to them? Or are you just blowing smoke out of an alimentary orifice?
You dont have to believe it. You cant even conceive the Futures market operates on margin.
Btw, No account I have will even let you trade Futures without a MARGIN account.
