I just want to use Bitcoin as a currency. I honestly do not care too much about the small differences between the two chains. They both have SegWit which will allow the Lightning Network which will allow for fast, cheap microtransactions.
Not really. BCH doesn't have Segwit, doesn't fix tx malleability and obviously LN can't play with tx malleability without other workarounds (?). It's just "bigger blocks".
Didn't BCH fork off after the Segwit lock in? Or did they fork with a version that did not include it?
Would make sense as Wu would not want to expose his AsicBoost usage once SegWit gets activated. Much easier to just create a whole separate chain where he can continue to use it to mine blocks at an advantage.
No BCH doesn't have SegWit. And that was done on purpose, because of Asciboost as you already have mentioned.
And yes Jihan can mine blocks at an advantage with that. And he can mine it alone, for himself. Although Bcash difficulty has reduced much and it may be more profitable to mine it, at least for some whort while, I really doubt that many miners will switch over. Therefore Bcash will remain extremely centralized. In terms of mining, protocol development, mostly in everything.
