Avoid Poloniex!
They have dropped my withdrawal limit to $0 - in response to my uploading a valid ID card. $10,000 worth of alt-coins that I can not access. Unbelievable. They do not answer support requests.
They seem to be attempting to steal the coins.
How that happened?
I made withdrawal week or two ago and everything was fine.
I've never verified account or something and I have 2000$ daily limit
