This is phenomenal information for anyone who is not aware.

Bitcoin Cash has a form of emergency difficulty adjustment, which is how it managed to continue being mined the last couple of weeks. Bitcoin (Core) does not, which means losing miner support is catastrophic.

Given the most recent mining profitability shows Bitcoin Cash at 140%, this could be dangerously close to happening. That 140% may not include fees and could be overestimated by as much as 25%, plus there are switching costs when changing your mining, but still...the arbitrage is already tempting.
