Assuming we are in 2072 where blocked rewards 0.0007629 BTC per every 10 minutes. And Halving BTC mined in cycle 160.2172 BTC
How can mining be commercially profitable in this situation seems very difficult to me.
Assuming that mining power consumption, electricity costs, and maintenance costs will be lower in a tech-driven economy, what will be the condition of the BTC market if BTC mining blocked mined cycle approach zero?
As i said earlier,
difficulty adjustment will make mining remain profitable where only miner with efficient ASIC and low operational can survive. For example,
if all other variable remain same (same Bitcoin price, ASIC type, etc.), the difficulty will be adjusted to only 1/2^13 of current difficulty.
