I'm in the small group that thinks bitcoin cash will not only survive, but thrive. I have my doubts it will overtake btc but anything is possible. Both can coexist and I see them rising and falling together. People love bitcoin so much.. they are not going to reject another version, they are going to embrace it. It's not like bitcoin dark, unlimited, etc. It's accepted as a genuine hard fork, it's currently #4 market cap. It's not going anywhere and will only rise. Opinion only :p
