I understand BCC/BCH is similar to lumen (but 1:1 ratio based airdrop).
BCC/BCH is just an altcoin is being created with air drop plans based on snap shot of blockchain as of August 1st 2017 12:20 UTC.

Yes, it will be a new altcoin with exact specifications similar to bitcoin but with 8MB block size and with other segwit proposals and finally it will start its life with pre-mined blocks. (pre-mined blocks are being copied from bitcoin's blockchain).

Why big hype on BCC/BCH and how they will survive 51% attack ?
