It would take you 5 minutes to do it.
For example I know I am going to receive € 50,000 in Euro's this year from my European clients. It's Jan 1st and the exchange rate is 1.2888 so that's worth £38,819. I fear that the Euro is going to weaken, so I short the Euro with a €50,000 spread bet EUR/GBP @0.7763.
Today I receive my Euro's from my client but with the exchange rate at 1.407 it is only worth £35,536 a loss of £ 3,282.
However I close out my short spread bet @0.7113 giving me a profit (0.7763-0.7113 x 50,000) of £3,250 on the trade.
Net result - a cost of £32
Anyone can do it for any amount.
