What do I do with my shares of FTCHQ?

Serious question what do I do with FTCHQ?

I have 34 shares of Farfetch and they are bankrupt I think. So value of zero. My costs are a little over $2000. Can I sale for tax loss purposes? Do I just hold on to them in case they come out of bankruptcy? I’ve never had a stock go to zero before so no idea what to with the shares and I hate seeing the red in my portfolio. Any suggestions?
