You can use energy that would otherwise be wasted https://cointelegraph.com/news/oil-companies-will-dominate-b... or clean energy like Nuclear
> What you call energy waste others would call effort
This is my whole issue with it - effort doesn’t have to be tied to wasting energy, but it is in Bitcoin. Why would people call wasting energy ‘effort’ in a system where wasting energy wasn’t intrinsic to the system itself.
Is PoS strong enough to still be 99% as useful?, I don't know, these are all experiments
If you are looking for it to be a currency, traditional currency seems to perform better.
If you are looking to invest in some speculative instrument on the basis that the value is going up then Bitcoin and poppies seem to be good ideas.
Nic Carter has a good piece on this: https://www.coindesk.com/the-last-word-on-bitcoins-energy-co...
Venezuela is the living proof of a government that makes decisions with the only objective of keeping power, WHATEVER IT TAKES, even if it means to the reduce quality of live to a 10% in less than a decade.
So bitcoin, and many cryptocurrencies, are at least neutral in monetary emission. Yes, it's not based on economic analysis, therefore is sub-optimal, but equally predictable by every actor, full transparent, no possibility of inside information or conflicts of interest.
The problem with Bitcoin is that energy waste is inherent in its design. As Bitcoin value goes up, the value of a Bitcoin relative to energy changes, which encourages more mining, which results in higher energy spend and emissions as the algorithm difficulty adjusts to the new hash rate.
Generating 10,000,000 bitcoins could be done at low energy with a few miners - but the more valuable they become the more energy they use.
My issue with Bitcoin is that while other industries try to save power, Bitcoin tries to waste it and waste is built into the algorithm.
And the more popular Bitcoin gets, the more our planet gets polluted trying to make magic numbers on a ledger.
