| Newton's 3rd law: Proof of Work and Proof of Stake both waste tons of energy, and of course, the entire economic system both of them are trying to replace also waste tons of energy. The problem is, Proof of Work is very objective and measurable, which is why most people criticize Bitcoin for its waste of energy since it's so easy to measure. But proof of stake and the legacy economic system both lack such objective measures, which is why it's hard to compare them. The term "stake" itself is subjective and doesn't take into account the economic ripple effect it can trigger as a result. And these ripple effects DO exist, it's just that most people are not aware of them and just take for granted. Which is why I think it's crucial that you study the history of money before you can confidently say you understand "how money works". This is not to say proof of stake won't work. It's just saying that there's a high chance that there's hidden cost to proof of stake which in the long run can map to the amount of energy wasted by proof of stake, which is backed by newton's 3rd law. You can't create energy. Everything that happens on earth is simply a transfer of limited amount of energy from the sun. If this sounds all woo-woo to you, that's why I suggest studying economics. I personally think the only way to overcome energy consumption is to come up with innovation that's as different from newtonian physics to quantum physics. |

Bitcoin is estimated to cost $2.5 Billion dollars per year [0] to validate about 77 million transactions per year.
Visa processed about 100 billion transactions in 2015 at the cost of 12 billion dollars (revenue - net income [1]).
That makes Visa 270 times more economically efficient for cost per transaction [2]. Also, I get many other benefits using Visa like fraud detection whereas bitcoins 1 way transactions make them extremely susceptible to hacks.
The economics seem pretty obvious to me.
