when most of us were doing the same when we received our free forked coins 
The only good use for all the bitcoin forks. Bitcoin Cash, Bitcoin Diamond, Bitcoin Gold, Bitcoin Private, Bitcore, (did I miss any out?) were all at their highest price in terms of real Bitcoin immediately after forking, and all have done the exact same thing - slowly lose value, with the odd pump-and-dump here and there to keep the sheep interested.I'm glad I dumped all that trash ASAP, and increased by bitcoin holdings in the process.
Dumping ASAP isn't the right speculative play, you would have made some nice money if you held BCH during that mega pump. Don't forget that bitcoin has also slowly lost value ( down over 80%)
when it comes to bitcoin price it is never about how much it has dropped from its ATH but it is always about how much it has risen in the long run. and in the past 2 years price has gone up from $900 to $4000 and that is a rise.
besides when it comes to owning something as a long term investment it is about how much potential it has. even if bitcoin has dropped 80% from the ATH it still has a lot of potential to rise to that ATH and beyond but BCH does not have any potential and it losing value means game over.
