What kind of personal information required to withdraw in poloniex? Is that a new rules? I have made some withdrawals (btc) from poloniex to my personal address some time ago, but as I remember they did not ask me any personal information.
It looks like it depends on how much you want to withdraw per day. Under $2000/day and you can remain anonymous I think. It's new rules they started a couple months ago.

That's why I had not been asked any personal information because I only made small amount of withdrawal

. Thanks for noticing it..
