BCC will never ever came close to BTC fame and its acceptance worldwide.
If the LN is not activated in the future and the transaction is very slow, Bitcoin Cash will be more dominant.
Bitcoins cash is just like altcoins and it is again just rubbish in front of bitcoins. I strongly believe that they are never ever going to touch the prices that bitcoins are sitting at. It is just ridiculous to even think that bitcoin cash can ever be more dominant in crypto world than bitcoins.
