It is not something new, no need to give warning like all hell has been let lose, bittrex locked my sis account for months back in 2017 and when the account was eventually unlocked some of her assets were sold and somethings not in place,
Bittrex is no longer what it use to be, I remember bittrex was like the binance of this day, many project would give anything to be listed on bittrex, ummm... how the mighty has fallen.
