Still waiting for a response to my support ticket I submitted two weeks ago. Withdrawal levels for my 3+ years old account were set to 0 without any notification or warning. I did nothing wrong. I traded from time to time. They request to do verification. The simple verification (by providing personal data) did not work because it searches data in a database and that database only contains information of US citizens. So I need to submit ID etc just to make a simple $400 valued altcoin withdrawal

Bittrex has been my favorite exchange for years. I'll never ever trade on this platform again.
I'm in the US and the same thing happened to me....I submitted my docs and everything and their "system" still refused to validate me....they then asked me for this:

That's after days of support tickets and multiple validation attempts with accurate and valid identification....so....there's something else going on here.
They were my favorite too ---> for the liquidity, but ---> the fees were cheaper on other exchanges.
