How do I get rid of this XNK ink?

Alrighty, I have sold and bought on Listia since around 2014 on until a little after they started the whole XNK Ink thing.  You know where everyone was forced to turn their Listia credits into XNK.  After that the credits just sat because the amount someone wanted in XNK for one thing was just stupid. What bothers me more is I have sold 100's of USD in items and now all I have now is 33 cents in USD worth of XNK (874.02)! How do i get rid of this XNK when I do not deal with any type of cryptocurrency? I mean it is bad enough I got screwed over with point value when they switched to ink and now they are using a new Listia currency called POINTS.  Nothing on the site is accepting XNK ink to buy anything and Listia has not offered to convert that ink into their new points. SO what the heck am I supposed to do with it?
