I moved part of my cryptos from Kraken to Bitstamp months ago and that has been one of the best decisions I have taken in my life, I only regret not having moved all of them.
 Kraken is a headache in all senses, soon or late they will make you angry for one or other reason. I lost a lot of money time ago because of their buggy trading engine, I could not close positions when they where on profit and I had to do it later on losses.
 Now, with this unbeliveablely unprofessional update, they have stolen a lot of people's money again with margin trades that where open while the site was down. The funny thing is that they even have charged the margin fees in the down period, which is insulting at least.
 I could not close my margins with porfits because they were down for 3 days (when they had anounced 2 hours), and now I have to do it with losses again.
 Cannot wait to see the withdrawls active again to run away from these thieves.

 Bitstamp works quite well and confidently for me (the only problem is they don't have margin trade but I can live without it now), but I am sure any other trade will be better  than Kraken. Just avoid Kraken and you will skip a lot of problems and anger.
