Read this as well, some important information by a fellow victim @ https://www.reddit.com/r/Bitstamp/comments/7pwi77/how_i_did_to_get_answers_from_bitstamp
I don't know if you have recorded everything before they closed your account?

Edit:
I just read their proof of reserves from their website and it's dating from may 2014 (where is the fiat reserve, equity and liquidity balance sheet?). The gut feelings I have line up perfectly what I suspect it to be. I personally feel this will end up very badly and an old meme of 3 years ago regarding Bitstamp going Mt. Gox might have been right after all... we'll see.

Is there any representative of Bitstamp here on the forums? Please update everyone, including all (potential) clients about this situation and your liquidity. When was the last time you were audited?
