The difference is I've had my account for years, used them successfully in the past, always had 2FA and never had an email regarding any unauthorized login attempt. So I have no clue regarding what's happening.
The worst part of this is that now I can't even withdraw my funds, so they've basically taken my funds as a hostage... Let's see how this plays out.
PS: I've successfully managed to withdraw from falling exchanges in the past... So something's definitely wrong on Bittrex.
Yeah, it sucks. In the first place, why would they give me deposit link if my account was disabled?
I could have gone with Kraken and have over 9BTC now.
In regards to your issue specifically, Kraken hasn't yet opened BCC deposits
edit: one user here suggests asking them for help in their slack channel, but it seems to be closed. At least I can't seem to be able to join.
Bittrex is now doubling their security after the fork ends. My account has been disable the withdrawal. I just create a support ticket regarding my problem and they give me an instruction to verify my account. Luckily, I managed to withdraw my balance. Just be patient because they are just updating their system due to the fork.
