BCC already immensely successful. $1000 in November.
That's why I bought some BCC... the BCC price chart looks ridiculously similar to any other alt coin, like Dash, first PUMP, then hitting the bottom followed by raising up to the ATH.
I still believe in Bitcoin, but BCC is really good for speculations and we can make even more bitcoins by trading Bitcoin Cash.
Today when Segwit locks-in, we can see a good rally in both BTC and BCC, but you'll probably get more profit with BCC and selling tomorrow.
BCC is going to be the preferred Bitcoin by miners and retailers. Average people don't care much for social conventions of using the "original" and these conventions breakdown with technological innovation. That's why ETH was seriously feared to flip BTC. BTC is like a cell phone from the 90's, it's useful and necessary but when you have an smartphone it becomes obsolete. BTC sycophants think their coin is a priceless artwork that will continue to appreciate in value for their entire lifetime and beyond but I don't think this will be the case. If something better comes along, like a copy with significant improvements that will be preferred, just like the smartphone. BCC has improvements on BTC and who knows, might utilize smart contracts in the future while BTC is left behind. I'm sure BTC will retain value but it might be superseded by BCC in the future.
