OH sorry about that ... im in the UK. Thanks
IIRC, Coinbase supports a British pound (GBP) and Euro currency but you can't directly buy on the Coinbase pro exchange platform.
Those bank transfers will take approximately takes 3-5 days in business days, at least you aware of this and not being frustrated waiting days for your transaction to be confirmed fast.
It might be good if you will read this article that made by Coinbase for more awareness.
https://help.coinbase.com/Just bear in mind that they had poor support.
Alternatively, you can buy on Bestchange or Binance exchange platforms or do your own research.
