ETC is gaining serious traction. It makes sense to hold some of it
ETC is open to double spend replay attacks and is barely mined so is highly unsupported and insecure. It's also about to suffer a serious 51% attack. Gud luck with that coinage.
And this is supposed to endear the community to ETH investors how exactly? The fact they can roll back the clock in pursuit of their precious investments and then blow the opposition out of the water at will?
Good luck putting that on a flyer. It's over.
