I believe we might have to move to hybrid PoW/PoS down the line (next 5-10 years). We need TPS speed from PoS but we might need to keep Miners to ensure proper circulation of coins.
Validator coins scale very fast (1500 TPS). Not all BCH users will full node (DL whole chain), thus SPV which still works with PoS or PoW/PoS Hybrid. Unless ASICs become far stronger.
