The Bitcoin mining can be unprofitable. And if the percentage of good miners stops, then the number of transaction/block solvers would reduce. And then sending bitcoin will take more time and be more expensive. So this is the basic scenario.

But, mining costs around the world vary greatly, so it is possible that mining can shift to various regions where the price is cheap. Liquidity will also be affected, because miners may not sell below their costs so that it will function as a natural price floor. But in the end, 1 BTC is still 1 BTC, and most people who mine do not really care about short-term price volatility, so they will only continue to accumulate it.
