I am a UK resident and I am buying some land in France for the price of about £25000. I don’t have to pay this sum for 3 months. In the light of Brexit, I am thinking of hedging against a fall in the value of the pound in this time. Can I simply put £25000 into Revolut and change it to euros? And leave it there for the 3 months. Is this doable, reasonable, the best approach?
