mate think of a scenario -
somebody lure you to invest money say 1 million [ buying a car ], and make you partner in business for certain %age. after business running expenses [ driver salary & maintenance ] every month you get an x amount [ with an imagination that your 1 million is intact ] as business profit.
one day you decide to pull the investment out [ sell your car ]
after deduction of business running expenses the profit you received during investment period was 0.05 million, and the investment value has depreciated to 0.70 million
now do the maths .. final loss is obviously yours
