we will know the answer at the next difficulty adjustment in 6 days.. BCC has fast difficulty reduction, if that kicks in and the difficulty goes down, miners will hop en masse while starving the btc chain. That is the moment of truth. Right now, everyone is just counting their future bitcoin earnings not thinking for a moment that value of their prized coin is about to be challenged in a serious way
And what is it going to change?
The price is determined at exchanges, while traders don't particularly care about how long it takes for transactions to confirm and how much people have to pay as fees. Even if half of all the miners all of a sudden switch to mining Bitcoin Cash will it help its price, and if it will, how exactly, i.e. by what means? The mining difficulty of all shit coins is next to nothing but that alone is certainly not enough to magically resurrect them and keep alive. Really, if no one is going to use BCC, what is the purpose of all that hashing power accumulated by miners that would amount to mining almost empty blocks?
