Every fiat currency, even the worst/weakest one has demand as long as the country and the population of it exist. Pound hasn't exactly been used for anything outside UK for a very long time either, so there is nothing changing there.
Can the UK print more money to stimulate economy definately not really...who gona buy UK debt bonds ?
There is no need to have anybody buy your national debt to be able to print fiat. That's what US does and not many other countries. They can just print money and cause inflation domestically like countless other countries!
So every top financial person knows there is no demand for UK pound anymore
There really has never been a considerable demand for UK pound before this either.
My forecast will be pound will fall hard against eur and usd Europe economy is in much better shape then UK.
All three will fall but not hard, at least not at first. The deindustrialization has hit all of Europe hard and energy crisis alongside the armed conflict they are supplying while enduring wave after wave of refugees is shrinking Europe economy. But it's a slow process that can only turn into a catastrophe (tank hard) if something significant changes like if they decide to enter a direct armed conflict instead of the current 4 proxy wars they're supplying.
