Bitcoin Cash is scheduled to go through the halving process in May 2020. The halving event will reduce the network rewards by half from 12.5 BCH to 6.25 BCH. Halving happens every 210,000 blocks.
The halving event reduces the inflation of the network. The reduction in reward will force BCH miners to shift their computing power to the Bitcoin (BTC) network, said Dan Hedl. He also predicted that the price of the BCH would slump down considerably.
10/ As the price of BTC increases, the value of the block reward increases (security follows price). As potential revenue increases, more hashrate comes online chasing that new profit. The higher the hash rate of a cryptocurrency network, the more expensive to 51% attack.

The only way to protect this from happening is if the network draws more users, and there is a spike in the network identity. Vitalik Buterin, the co-founder of Ethereum, has proposed the integration of Ethereum in Bitcoin Cash as a short-term solution for their network’s scaling problems.
