I still don't think BCH can compete with BTC long term, but markets can stay irrational for a long time. I'm glad there's a blockchain for big blockers though. Hopefully, resulting in less drama.
Perpetual onchain scaling destroys decentralization
BCH also has a very weak dev team when compared to Bitcoin Core. It's like high school team against pros.
Given all that, the only possible outcome is that one coin will go to $0 in the long term. My bet is obviously on Bitcoin. All the short term price movement doesn't really matter. I'm not trading it.
Without SegWit, it will never get future tech upgrades like LN, Schnorr, etc. No way it can compete with BTC or LTC.
