I have no idea about how this leverage thing, how it works..? I have never tried but this seems convincing based on this wild up and down fluctuations $30k-$40k lines.
It's simple, borrow 100x of what you have and trade with it... 100x profit but 100x loss too, so if corn goes down 1% your collateral gets liquidated. Amazingly there is no lack of math-challenged idiots who think it will never happen to them.
