Ripple fans hold and invest in XRP because they believe that after court all claims against this cryptocurrency will be resolved. Afterwards all Ripple haters together with SEC will nervously panic, when XPR will pump to the moon.
All haters? we'll if it pumps, then that's good for those holders of it but mostly, they don't care if it pumps or dumps. The lawsuit doesn't seem to be an issue anymore.
XRP is just still around and regardless of the lawsuit, the trades in different exchanges are just continuing.
