Same problem here.

Until yesterday everything ok, legacy account with 2fa enabled, 16 eth deposited from my mining activities.

Yesterday morning login on my account and they ask me to verify my account.

Ok, no problem, perform enhanced verification procedure, all right my account is now enhanced.



Login again on my account and now my account is locked!



Open a ticket, only automatic reply.

Ask me for a selfie with my face, personal id and a paper with write bittrex and yesterday date.

Not another reply from support, now wait for another news.
