Too true Stoop.
The exchange rate loss would not occur to those who intend to live in Turkey permantly, as you would not convert back, and the GBP would be of no use to you. Needing GBP to travel back to UK to see your roots now and again would be of minimum impact.
So you need to ask yourself:-
How much are we talking about? (less than five thousand £, i'm going back to bed!)
Will you need to convert back into GBP and have forex impact.
If substanial amount, (i'm out of bed), look at other possibilities, longer term deals/stocks, brick & mortar etc, investments with guarantee capital repaid.
Two questions Stoopy, do you have a lot of money then
?? and what did you use to be between 18 and 31??LOL.
