Bitstamp stealing my ID and banking details ?

[jdebunt]

this is true only if the attack is not performed while they are handling your id or someone other id, otherwise you might be in trouble, id can be validated offline like bitcoin transaction

Not sure if Bitstamp verifies internally or uses a third party though, so your data is always at "some" risk....

Providing IDs and sensitive information to these sites is always dangerous which is why I am a bit hesitant of providing the same to any site, no matter how legit or secure they say they are. A bad or pissed up employee could sell them and then company's response would be that they were hacked, or company might sell it themselves (not saying Bitstamp will do this) or they might actually get hacked. So only do this if there is no other option.
