I was looking at ETH/BTC today and figured that it was a golden opportunity to flip. I'll hold the ETH I've gained very cheaply now and wait for the inevitable gains. BCC could end up being worthless as everyone dumps it for quick profit - and a great many will have flipped their ALT coins expensively into BTC (at a deficit) to try and catch the opportunity. They could end up bearing a reasonable loss or find themselves stuck in a long holding position to regain their margins - assuming that BTC continues to rise long-term. Time will tell :)
