Seems like Coinbase is soon to add BCH to their payment system. According to their blog they plan on adding Bitcoin Cash as early as January 1, 2018 (see below).
According to Coinbase, their main goal when on-boarding a new digital asset is to make sure that they do their due diligence and any necessary testing and auditing of their systems, to make sure that coins they support be safe.
Coinbase may be behind the curve when it comes to incorporating new coins into their payment system but you can rest assured that proper steps were taken to make sure that security is the number one priority. Since reliability is a major concern in the crypto space I'll gladly wait for this implementation to be finalized because as we all know Bitcoin Cash will soon be taking off if it's not already.
For future reference Here is what Bitcoin Cash is doing today.
