I would take 50,000 and buy shares when they are at a low. In particular,the trend in NBK is quite notable.Buy 9100 NBK shares at 5.42 shillings per share and sell at between 8.2-10.45 shillings a share.Making profits of 2.75-5.03 per share.Step by step until I get to 50,000 which would take about 3 trades on a good month.Do that for another month,calling it safe trade.
Pay back the 100,000 and then begin risk trades with my acquired profits.
