It's not the brightest, unfortunately. But BTC was the first crypto currency ever, and it will not die, I'm sure.
If BTC price of production exceeds BTC's sell price, I guarantee BTC would die within a year.
The ASICS Miners could dump btc/segwit and move to bitcoin cash if they made a larger profit.
Bitcoin is not a deity, it is a technical product as such it can die if the economic environment turn against it strongly enough.
Bitcoin supporters are continuing to ignored Major problems.
1. Insane Energy Waste
2. a Variable fee structure that can allow miners to manipulate the fee system to make higher profits
3. Limiting Onchain Transaction Capacity in order to force users Offchain
Any one of the 3 could put a nail in btc coffin.
