Margin lending is bad especially in a stock market.. I am old enough to have seen this before and without the net and great technology of today .. you couldnt even get in contact with a broker to place your sell order.. You sat alone watching the TV... helpless..unable to trade. No HC ..NO way to trade.
But figures I have heard of interest...
World stock market is worth 100 trillion World GDP is worth 50 Trilloin Derivatives is worth 500 trillion
