So long story short, I've been struggling with them In the past 13 days contacting their support to re-enable my account,
While their replied didn't give me any explanation when or what's the Issue with my account.
Keep us updated. You aren't alone. The only thing Bittrex has said is that only 0.1% of accounts are affected. I am very skeptical of that claim given the plethora of complaints about account locking that we are seeing over the past two weeks. I suspect they are including empty/inactive accounts in that assessment, and that many more people are actually affected.
I wish they would at least give us some explanation. We can only piece together some of the common links. From my observation, it seems like country of residence may have to do with it. It doesn't seem like anyone from the US or UK is having their account locked, for example.
