don't let the bad reviews put you off
Bit wary initially due to all the terrible reviews on here. But actually account opening (I live in the UK) was as smooth as can be. ID process using passport took literally 2 or 3 minutes before I was verified (at intermediate level). I added GBP funds direct from online bank via faster payments option and they were visible in my account within 15 minutes. Security was one of the reasons I picked Kraken and it does look ultra strong indeed - I have authenticator up and running, and a couple of extra options I have yet to decide on are also available. I really can't imagine how things could be any better. Don't let the bad reviews put you off
