Thanks velome.
Im also sticking with Kraken because it has low fees in exchanges from fiat currency (euro in my case). Neverthless, its a bit ridiculous that its server has low capacity. I also have a Bittrex account and never had this problem. Its very fast to setup and cancel orders and it has a LOT more coins listed, so i guess a lot more order traffic that Kraken...
Oh well, lets wait and see. Im also following Luc's suggestion and placing "panic buys". The worst it happens is to have to cancel the order 3 times... :)
Happy trading!
