This doesn't look promising but I would like to encourage if anyone knows any additional information, please share.
I found a note in my notebook that I send 5,644BTC to liqui exchange back in beginning of 2017
Sadly all the news / updates that I've found so far reiterate what previous members also told : it's dead for good. The report is shared by numerous news outlets :
They did state that they couldn't guarantee support after 30 days have passed since their shutdown message. I've also tried searching for an active twitter for the company but it also has been deleted.
I'm sorry for your loss valov88, but the transaction records aren't worth much at this time...
