I do not use Kraken, but as long as your assets were not seized by the exchange, your withdrawal should go through. Centralized exchanges do not process withdrawals per individual, many withdrawals are merged into one transaction and sent. BTW, how are you checking the bockchain for it, do you have the transaction ID?
I intended to only send to Kraken what I wanted to sell but mistakingly sent all that was in the wallet.
I am curious how you made this mistake, you have to be very careful when you are sending assets from your wallet to a centralized exchange, they can seize it and ask you for things you might be unwilling or unable to provide.
