@sky77, your logic is correct; BUT that is only assuming Bitcoin holders got their "free" BCC when the fork hit. If you didn't, then the combined value is completely irrelevant.
If you buy Bitcoin today, the BCC value doesn't matter. Why? Because you don't get a free BCC by buying BTC today - that has passed.
If you bought BTC last week and didn't transfer to an exchange that would honor the split, (e.g. Trezor wallet or Via BTC) then you still only have 1 BTC worth around $2700. Period.
To combine the two today for a "total value" is irresponsible and misleading because that assumes they are linked, which they aren't (they forked....)
When Etheruem forked last year, no one said "combined value". And when ETH value is referenced today, no one adds the value of ETC. Same will go for BTC and BCC. They are separate, independent and mutually exclusive. To say anything otherwise is incorrect.
@bitbybit, this is all true, and I agree except in the judgement in this context of calling it irresponsible. Yes and many (self included) have communicated exactly this to get BTC off the exchanges into a hardware wallet or one of the exchanges supporting BCC (such as ViaBTC) prior to the fork. To those informed this was clear before and after the fork, but I guess you can argue in defense of those who are uninformed about how the fork works.
