Sometimes people aren't doing things for reason, but they do because others are doing the same. People may argue BCH rising because it has more utility than BTC due to low fees, bla bla. But is BCH the only solution to BTC scalable issue? Aren't those 90-95 red coins among Top 100 coinmarketcap coins faster than Bitcoin and much cheaper than both BTC and BCH in terms of fees?
True, but there is a shitload of sha256 mining equipment around the world that is looking for the most profitable coin to point towards. BCH is looking more and more likely to win that mining hashrate.
Without majority mining hashrate, BTC is dead. Same can be said for B2X as it stands currently. BCH will survive and thrive no matter what happens with hashrate (new diff algo on Nov 13 maintains 10min blocks much better)
https://www.coindesk.com/bitcoin-cash-developers-set-date-november-hard-fork/Even though BCH mining seems more profitable at the moment, miners shift can't guarantee that users will shift to BCH too. As a result, BTC will sustain and when load of miners reduces on BTC, it will once again turn profitable mining option. So this cycle will revolve again and BTC will rise again.
I honestly don't feel promoting BCH is solution to BTC scalablilty issue, in any way.
