Just drop and dump it if you still have it. But can't blame this one because it has made an ATH and holders of it that didn't sell are still hoping that someday it will be back there.
But to tell frankly, there's no hope for this coin anymore and just look at their development, is there something new and interesting they're talking and developing on this one? I haven't seen any.
Since the split of BTC, development for BCH is going nowhere, all are the clusters without any clear direction. Not really hard to not see BCH at this state right now. For BTC, they can be slow to update and stagnant. But for BCH, they can't because they have to compete with other alts out there.
