Today my account was unlocked and i can trade and withdraw, but the ethereums I put for stake are still missing. I will update about this too.

I think that bitstamp is still a full legit exchanger, but on the internet is full of people unsatisfied or frankly scared by their very unpersonal approach ("we are working on this" is the only answer some people got after months of blocked account and after providing all requested info). Kraken seems to be a better option for European users nowadays.
