well currency will always change everyday due to the oil sales so the world currency changes with that.
but one thing wont change for now (dunno the future), and thats the value of the money.
Pound will always worth more than Euros and Euros will always worth more than US Dollars.
this means that if u are in UK u will pay less Pounds for more Euros, just like it was stated before on this topic

u can also check a currency website, there are plenty

i use XE cuz its always up to date
