re: Bitstamp withdrawal.

Might be some automatized safety thing, that wasn't exactly thought through very well?

Maybe something like: If IP address changes regularly, stop withdrawal. Something moronic like that.

Aaanyway...

Just bought 1 btc for testing purposes, and btc withdrawal works for me, as they always did. Arrived at my address a few minutes later.

NOTE: I'm not denying that some accounts have problems withdrawing, but at least we know that not all accounts are affected.
