With the power requirements to run the BTC network continually increasing... what is the long term solution? It doesn't seem viable that it can go on forever like this. Anyone have good insight? It's easy to just assume... "well there will be cheaper energy in the future" or "BTC will just switch to POS".... I guess I'm looking for answers with a little more substance and detail. Thanks!
Maybe it the remaining Bitcoins will be mined the price will be extremely high also for the fees. But remember that Bitcoin will be so much expensive than right now.
The higher the price of Bitcoins the more energy the mining sector will attempt to use. Raising the price of Bitcoins over time make the problem (total power consumption) worse, not better. See:
