My opinion is that bitcoin cash is a temporary phenomenon. I do not believe that this is a promising coin. Perhaps the miners will use this coin for speculation and pressure on bitcoin but in this game they set the rules and I doubt that you will have a chance to win. You can't sit at a card table with gamblers. Be careful with these altcoins.
Be careful about the hijacked coin (bitcoin). Segwit enables side chains, and their goal is to implement something like banks (lightning network) and they will push you off the BTC blockchain.
Sidechains are the governments DREAM. Something which can be controlled, and tracked. Blockstream recently said in their investor letter that Sidechains will implement KYC/AML and no longer allow semi-anonymity that Bitcoin used to give. KYC/AML means taxes and full control over every transaction and who is who. A libertarians nightmare.
So, BTC is going to shit. You better grab som bitcoin cash.
