Or just move over to Ethereum which is actually moving forward on proof of stake, which solves this problem in an elegant way. It also has major plans for scaling, which Bitcoin has ignorantly refused to budge on.
Proof of Work is a simple algorithm that has worked for over 10 years. Proof of Stake is incredibly complex and might be broken in implementation or from a game theory perspective. It also might be a huge improvement over PoW... it’s just too early to say.
