I am on multiple exchanges and some have come outright and said after the split, 1 BTC holder will have 1 BTC + 1 BCC after split...some havent addressed this question other than saying they wont support BCC...

What about online vs offline vs exchange wallet...will all BTC holders regardless of location now be credited with 1 BCC in this scenario? or just those who hold BTC on the exchanges mentioned above?
