I say Bill Gates is bad for the Planet. The reality is PoW is the only consensus mechanism that is secure today. PoS is not secure. It will never be secure. It takes energy to secure money, it is that simple. We will spend as much energy as is needed to secure the bitcoin monetary supply - the economic prosperity of the planet is at risk! For all those folks out there begging for PoS bitcoin, it will never happen. Yo…
What about proof of stake is not secure? I think it's clear that the electrical use of proof of work will become a serious issue if Bitcoin (or similar blockchain) becomes widely adopted. Do you have a suggestion on how to address that issue, or do you believe it's a non-issue entirely?
One can make an argument about transmission efficiency, and generation materials (and how renewable sources are more efficient), thus profitable for both the planet and the miner. But the actual use of energy? Get out of here. Tired arguments that I thought died years ago.
