I've had a kraken account and lost 15k usd on them because of their service.... had 190 bitcoins in bitstamp balance and moved them to kraken, it reached 6 confirmations in 30 mins and the money was credited in 4 hours (during the fall from 498$). Their sepa took 3-4 days (while stamp takes 1-2 days) and they dont have volume. If i sell 200 btc right now there the price will drop 5 euros (minimum). Limit is not very high since they banned my account for "suspicious activity" when all i was doing was selling my bitcoins on my personal account to my personal iban with all the documents sent. So im looking for another service like kraken, but better.
PS: Sorry for my bad english.
