Please share your thoughts around this claim:

"Fork-Attacks on bitcoin like Bcash and B2X might become infeasible after next halving; due to the value of mining reward becoming Fee>NewCoin"

You can Fork the block reward (New-Coins)
But all the economic fee-generating-activity stays on original chain
Miners must follow the User rather than New-Coin

I haven't seen any discussion around this topic, so I'm curious if I'm missing something..
