The fees on Kraken are a rip off if you're buying from UK. They compulsorily convert your gbp to euro first and that costs you an extra exchange fee for no reason. In SP's review about the fees ( see below) in November 2021, Kraken responded that if you buy through google pay, there isnt a fee. This is a flat out lie!. I brought 1450£ worth of crypto throught the Google Pay option and got charged a fee of 90 euro plus a bank euro transaction fee of 44£ on top of it!.
