there was a report that a chinese lady married with a poor man suddenly had $4b in her name. as reported, she used $400m cash to buy 4 business and hired thousands of employees who got paid 200% of average pay, and give free carwash, dry cleaning in the city. she bought buildings in blocks. now, tax man is investigating how she got this money. 2 yrs ago she has $0. her reply to the media is "i made $4b from trading futures with some luck and good instructor" the questions are two 1 how she earned $4b from her initial $8m in 2 years? the $8m is an unsecured loan. 2 why wouldn't she claim she traded forex where leverage is more. most internet postors think it is an impossible record and she just laundries money for somebody else.
