will get free BCH or will only exchange ?
You'll get the BCH in a lightweight wallet on your computer. You can then choose whether to holdthis or to send it to an exchange to cash in. It's a functioning wallet that you produce and thus you can go the other way and buy bitcoin cash and store it there.
