In this case you will be able to exchange your existing BTC funds to BCC on a 1:1 basis.
Exchange meaning if I have 1
BTC at your site at the point of the fork, I'll have to decide whether I get BTC or BCC? I can't get 1 of each?
What about future deposits, does that count for those too?
One way or two way exchanges, as in, can I get BTC for BCC I deposit (since you want to support both chains)?
