I see it as not so important what Bitcon Cash futures suggest that the coin is worth currently. A fundamental fact is how much mining from the current Bitcoin network is comitted to this altcoin. Antpool , which is owned by Bitmain, mines 25% if i have the correct numbers. https://www.buybitcoinworldwide.com/mining/pools/
Antpool will mine Bitcoin Cash if i understand all of this correctly.
I bet they will not say within a week: screw it, it was a silly idea. And return to Bitcoin.
