Hi,
I have question, if I will have on Bittrex BTC, Bittrex change BTC automatically for BCC? Or my BTC stay here and I obtain else + BCC for free?
Bittrex have promised to give you your BCC in addition to your BTC but they didn't say yet if they will let you buy and sell BCC so if they aren't going to open up a trade pair they will let you withdraw it to your own wallet.
Bittrex is a very good exchange as anything else would be outright theft.
