I will try to make this short, cos nobody have time for boring posts.
Im daily trader, trading crypto since 2013. Probably used all exchanges, but never Bittrex( thats before Aug 1st)
I had accoount on Bittrex, not sure when i open it, but never got any funds.
Couple of weeks ago i got email from Bittrex with login information to my account from IP that i didnt recognized.
I didnt have 2fa enabled, so I clicked the link in my acc. and disable it. After that i enable 2fa, changed password and send
ticket to support and asked if there is anything else that i can do. No answer, but website states that account will be disabled for
at least 24hours after contacting support. Great, np, i had no funds, so OK. Life goes on.
Last week, fork was happening and since my funds were in Poloniex, and they didnt say anything about matching BTC with BCC,
I decided to transfer my funds, 2.77BTC, to Bittrex. And that's what i did.
Fork happened, got matched with 2.77BCC, and went out for biz(doesn't matter)
When i got back home, BTC-BCC trading already started, so i was pissed off that i didnt catch the wave from bottom,
but price was still great to buy, 0.12, with LOTS of volume. It was already late, so i decided to go all in with my funds and go to sleep.
I setup everything, went allin with 2.77BTC, clicked confirm, and guess what?

ACCOUNT DISABLED. WTF???
Than it hit me that couple of weeks ago i dissable it and its not enabled yet. FUCK. Whatever, i went to sleep.
When i wake up, BCC was 0.4, x3+ from my wanted trade. Fuck it, lost 6-7btc. At least i was left with 2.77BCC that i was matched.
I decided to sell them at $1000, setup everything, clicked confirm and yes, ACCOUNT DISABLED.
Account is still disabled, my funds are locked, support is not answering. I also tried contacting Richiela on Twitter, LinkedIn and its
same as support, NO ANSWER. For the past 5-6 days im writing to support and they are ignoring me.
If anybody have any info on how to contact Bittrex or how to resolve this, it would be much appreciated.

Bittrex is known to basically suspend any accounts that have more than $1,000 in their account balance in total, that has not been verified. I'm pretty sure that this has been confirmed by their official support team. Sometimes i store a bit more than that and i seem to be fine, so maybe there are more variables than just the account balance alone. But you get the point.
Contact their support, at least their support is somewhat better than poloniex's. Hopefully they respond and unlock your account.
If they do unlock your account then withdraw your money straightaway. Try to negotiate with them to get your BCC profits back but unfortunately i don't think they will listen because of terms and conditions stating that they will not be held liable by you and software is provided as is etc.
Take this as a lesson - it's better to store BTC offline in a cold storage in a case of a fork, even if it means losing out on a few hundred bucks profit.
