Investing rules broken: diversify, high risk needs to be low stake, only invest in companies with good management, only invest in what you understand, only invest in honest companies whose books and actions seem fair and true, etc.
All in Siaf is the stupidest possible way to invest, totally reckless and based on simple greed thinking investing is gamble not investing.
I'm afraid your friend got what he deserved, he made horrible choices.
Last and biggest mistake he made is he had chance to get out for long time but not selling when down, no stop-loss, it is perfect display of how NOT to invest.
