Currency question

So i live here in the UK and i want to open an account and start investing but i saw that it gives me options about the currency i want to use i know that in a couple of years i want to move to a different country. What should I do? Can i change currency after i start investing?

In a few years there could be a whole new payment method with the evolving financial technologies so I wouldn’t think that far ahead as yet. You can get multi-currency accounts such as Revolut
