thats exactly what happened with alot of us from who were original users from 2014. Overnight they blocked access to withdrawals (but we could still trade, whats that about!?).
They would not allow us to close our and accounts and leave with our property. its another example of how regulations have enabled these types of AML/KYC scams to grow and prosper. Established scams like Bittrex can now always hide behind their AML/KYC policies and deny people their funds.
hopefully a nice class action against them one day when the extent of the abuse and how they have profited from their AML/KYC polices is fully revealed  

How long has DOGE been offline?  I believe I tried to withdraw some about 2 or 3 weeks ago and today I find it's also offline. 

Massive delisting of private coins on Bittrex on  January 15

Was the snapshot taken yet? I've searched a bit and I found some results about it being postponed. So if that's the case, you can simply withdraw the funds to one of the exchanges that are going to support the airdrop, and wait until they distribute XYM to their users.

What's up with Bittrex? Any idea what's going on there?

@VintageBazaar. Your suspicions might be very far away from the truth. This might be regulatory pressure by the government. I speculate exchanges that have not yet asked for KYC will begin acting similar to Bittrex because those exchanges have been used liberally for money laundering. Bittrex might only be cleaning their exchange from accounts suspected used for money laundering. There will be innocent accounts locked as casualties of this, however.

I would like to ask if bittrex maybe restore withdrawal for legacy accounts owner as poloniex did?
Have some funds there and don't trust them. They  are changing rules constantly :s

CEXs are not doing fine in this market and bittrex is getting out of the news. No top project from the exchange, no volume, reduced users and was never mentioned with project that had a huge price movement either in a day or week. If it continues this way, bittrex might be one of the project that will be swept off in the next bear market.
