Bitcoin [BTC] halving is less than 15 hours away, the run-up to the event in the last couple of weeks have been quite exciting. Reportedly, more than 30% of the BTC mining ecosystem presently employs the S9 miners.
Currently, the percentage of total mining hash-rate of BCH and BSV is around 1% of the total hash-rate for Bitcoin [BTC]. The hashrate on these altcoins is currently around the 2018 and early 2019 bear market levels. While Bitcoin has seen a 2.5 fold increase since then, BSV and BCH hashrates continue to remain in the lower range. After halving, some of these systems might look for other SHA-256 algorithms to seek profitability.

However, evidence from the Black Thursday crash of March 2020 indicate that switch to Bitcoin Cash [BCH] and Bitcoin SV is unlikely. The S9 and S15 miners which became unprofitable with Bitcoin after crash in March did not switch to BCH or BSV.
Of course, the drop in the prices of the entire market restricted the switch over. Currently, Bitcoin is trading around 10% higher than the value before the crash, while BSV and BCH are down 7.5% and 15%, respectively.
