If you don't have a crystal ball and you can't see into the future then why on Earth are you writing off the UK because we are ending out EU membership? Tell me. Why do you think the UK is going to have huge losses? Does that not make you a negative fool? It is like saying there will be world war 3 soon. It is possible but you don't know unless you can actually see into the future.
The financial experts say the UK will have losses but it was financial experts that said the Greeks should get rid of the Drachma and take the Euro. It was financial experts running the big banks like northern rock when they became bankrupt.
I hope that when they trigger article 50 these silly fools will move to the EU.
