If you transfer ether to kraken you will have to wait one day for your funds to be available!
Recently found out that you can load your pre-sale wallet directly into Kraken, here is the link:https://www.kraken.com/ether
I find funny how nobody ever mentioned this officially.
Looks like the ethereum guys are pretty much busy dumping their coins, they don't even care a little about informing the public!
What a shame really, I was expecting much more from a project that gets 18 Million dollars!
