Guys, thoughts? We need to change Bitcoin to proof-of-work (PoW) to proof-of-stake (PoS), right?
From what I know, right now it costs over 1000$ to mine one BTC.
From what I remember - it may not be very accurate - the PoS coins value keeps degrading over time (whales just sell the coins they get for free).
All in all, while I agree that the global cost of energy for BTC is huge, if we change this we may end up with a very very cheap Bitcoin.
