Saying never? I would like that this can be true, but, it always can be a 1% of chance for the opposite scenario
If it's not profitable for anyone ever after difficulty adjustment, most likely Bitcoin is on verge of death due to abused critical vulnerability on it's protocol and whether mining is profitable/not doesn't matter.
Bitcoin price is just supply and demand (and manipulation). If a miner can no longer mine while remaining profitable, he can:
- Stop mining, sell his hardware
- Stop mining, keep his hardware in case the price goes up or the diff goes down
- Keep mining at a loss, hodl the mined BTC
- Keep mining at a loss, sell the mined BTC
I agree but note that it doesn't make sense to keep mining at a loss (if you don't have to) because you can buy the bitcoins for a lower cost.
Maybe because few people think Bitcoin freshly mined have premium price since it's not tainted, not that i ever people who actually try to buy/sell it.
