Its cos the Lira is the Currency of a Country run by a Liar!
Well you can buy Lira everywhere in UK at the moment, but of course if the value plummets further
then controls may well be exercised! I intend to buy £500 soon, just watching the rate, and then if it goes up even more I would be surprised if it got above 3.6 as the longer the current situation lasts the less impact it will have, and if it looks like he will survive and the Country isn't heading for revolution then it will stabilise and start to drop.
I was advised that Mid January (now time) may be a good time to buy.
But at the end of the day, buying foreign currency isn't too different from handing over money at the window in Ladbrokes!
