Revolut is an option I would recommend for this which is available across Europe and Australia.
It’s great for when you go on holiday, they support currencies from over 20 countries and an account will enable you to trade US stocks and commodities as well as precious metals and digital currencies. BE AWARE: you cannot withdraw your digital money to a non-custodial wallet which essentially makes it an I.O.U. Alternatively you could use https://privacy.com/ as well but only if you live in North America.
