Most of the famous exchanges have already announced that they are not going to support BCC.But poloniex has said that they would just wait and then decide what to do.So,we could not exactly say that poloniex would give you free BCC for your altcoins,but there is still a chance for you to get free BCC.
i thought only some wallets will give free bcc, maybe will know this week if polo will really give free since there are none who got any of it today,then maybe it's not for now.
