I just started using them for the low trading fees, and then went to transfer out some BCH (cause that's what Bitmain takes atm) and Kraken either sent it to the wrong address (there is only two hops in the block chain so far) or it's stuck in one of their storage wallets as it never even attempted to go to the wallet address i provided, at least when following the blockchain of the transaction. It's now sitting in a wallet with like 28k BCH so I assume it's a storage wallet. Am in contact with their support team (which seems slower than other exchanges I've used) and will see what comes about. $1700 in BCH may be gone.
I'm a bit hesitant to try and transfer out the remaining BTC I have in there to another exchange. It seems to go into their exchange just fine
Just curious what others experiences are when transferring or trading on Kraken
