Why don't you make this simple to understand that who had BCL at that specific block number will receive the coins. For example I had Bitcoins and also got BCH but BTC remained same while I dumped BCH when I saw good price. This thing cut off my way to get BTCC for good. That means most of the people will have to buy simply.
It is the only way to qualify for forked coins, but I am skeptical whether many people will really buy BTC to get this fork. It's not getting people as excited as it did when the first forks came out.
