Finance has always been a bit of a black art beyond current and savings accounts, so I'm hoping this makes sense.
In light of the possibility of Britain leaving the EU (that isn't the actual reason, more of a reminder for me) I'm interested in ways of spreading my savings around a bit, mainly keeping a portion of them outside the UK / invested in a different currency.
What is the easiest way to do this?
Are there banks where you can open a bank account without being a citizen of that country without having to visit the bank in person? Are there UK banks that allow you to hold savings in a different currency? Are there any online services for investing money that aren't tied to any particular country?
(Note: I don't object to visiting a foreign country to open a bank account, I quite enjoy travelling, but ease of access is important)
