It is what it is: Option 1
Sooner or later a lot of that coins will appear in the market, affecting the market numbers (price, volumes...). Any other option is absurd.
I don't think we have to "obey" CMC ... Who are they ? To me they are acting this way due some hidden interests, unknown for the rest us. What we have to do is to listen the BitCore community.
At the end, if CMC doesn't want to be rational, we can choose to obey or to adapt ourselves to the new situation considering more options, including a Bitcore fork to undo transactions for unclaimed BTC coins returning them to circulation again (via more airdrops, or any other method) to satisfy these new CMC rules "made expressly for us".
I'm not in crypto to obey arbitrary decissions from third parties, so it should be a BitCore community and developers decission.
We can decide what we want, but not what CMC puts on their page. But if you wanna go toe to toe with the no.1 place to go for information about crypto currencies, I don't think that's a good idea. I don't like it too, but trying to compete with CMC about credibility is IMHO a battle you're going to loose. We need to find a compromise in a diplomatic way, at least for starters. What doesn't mean I wouldn't prefer option 1. 1 would be tje ideal solution.
What about the credibility of the coin? Having to explain those 8 million, every time someone asks. And never having an unquestionable circulating supply.
Has to be option one. Diplomatic is the only way, but option one is the only reasonable option.
