Pretty sure I will have to start an account over, I never verified for years on Bittrex or there anyhow.
Your account should still exist at Poloniex, flagged as "Verification status: Legacy" with a withdrawal limit of 2k USD/day (verified accounts have a limit of 25k USD).
Legacy accounts will be frozen at some point in Q1/2018 according to
this press release, it seems most unlikely that the new owner will change anything regarding that verification requirement.
