It's a pity that I left the kraken trade, because for the Kyc system, I have to attach a Current Account (Last 3 Months) if there is no credit card statement and the like. I think the account book is very personal. So I avoided it and moved to binance.
I got the same problem. I'm using Kraken for years and was very happy to not have to give any ID proof during all this time. I told to many people to go there. I've been upset with the last change. No choice but I sent all the needed papers. I need at least 1 exchange on which I can rely for a quick bank transfer out, and Kraken is unbeatable for this matter.
