Something is seriously broken with BTC deposits on Kraken. Yesterday I was given BTC deposit address, which is not unique as I realized later after sending BTC to this address and wondering why it is not showing up in my kraken account - in blockchain, there are 183 transactions depositing to this address and current balance of this address is over 600 BTC. This is some serious bug as I don't understand how would kraken understand which deposit was mine (thanks god only little over 0.5BTC), because deposit addresses must be always unique (or reused in some safe way). This wrong deposit address is still showed in my account under deposit BTC address with status "expires in 5 days". I've create support tiket for this issue under my public account id "AA70 N84G UGR4 I6QA".
Is anybody competent able to comment how will kraken solve this issue?
It is seriously broken. I've created a support ticket for this issue too (filled in my username "mctinus" in the public account id field instead of my "AA24 N84G BWTX E7OY"). What really worries me is the fact that the faulty Bitcoin funding/deposit address is still showing! Probably for other users too. So people unaware of this problem will deposit money to a faulty address. It's 48 hours after submitting my support ticket. I'd expect some reaction by now or at least blocking of the faulty address. But I've had no reaction from Kraken!
Everyone affected by this issue should do as you've done - create a support ticket about it. Support is limited over the weekend, but we'll be replying to these tickets today and tomorrow. I agree it's better to remove the address, and I'm recommending we do this, but it has stayed up for a bit because others on the team thought it might create anxiety for users if the address just disappeared. Nobody has made further deposits to the address, so it hasn't been an issue so far.
The bug that caused this has been fixed now, so the only issue left is returning funds. We estimate that we can credit everyone for their deposit within 1-2 weeks. But as I said please create a ticket about it.
