I agree with martinhyl.
Kraken has been having major problems with deposits and withdrawals, especially USD deposits and withdrawals.
The customer support was very slow to address this issue, until they finally said no more USD withdrawals.
Kraken CEO Jesse Powell recently posted a comment on CoinDesk denying that Kraken has suspended USD withdrawals, even though many of us had received an email from Kraken advising us of that situation.
My concern is that Kraken's CEO Jesse Powell is another Mark Karpeles.
Why do I say that?
Jesse is a kid who made a lot of money trading magic swords and things in computer games.
He "came out of retirement" to start Payward/Kraken after he saw in 2011 that MtGox was messed up from the inside.
Yes, as Kraken has faced difficulties with their banks over the past two months, instead of just telling us the truth, Jesse has blustered and covered up just like Mark Karpeles did - until he couldn't cover it up anymore. Then and only then did he come clean with us, the customers.
I have very little confidence that computer gamer Jesse Powell has the knowledge or integrity to run a financial institution, which is what Kraken is.
If he wants to change my mind, he needs to start taking RESPONSIBILITY for the performance of his company immediately, instead of blustering. He needs to put in place 5 Parties Model of governance. And he needs to start processing withdrawal wires in less than 3 business days.
