You can flush both down the crapper quite simply because they are 'Chinese' driven.
You can see the price of Bitcoin Cash or WTF its called. Its crap and will always be crap and crap is worthless.
No need to flush them! They are cows and all we need do is to go ahead and milk them all we can and feed Bitcoin fat, as simple as that! Interestingly bitcoiners are getting ready for that by piling up as much Bitcoin as they can. Someday the unfriendly friends of Bitcoin will learn to let Bitcoin be!
