You can’t even mine with Bitcoin PoW and break even, unless you buy ASICs, and even then, the % ROI is way less than what you’d get with Ethereum PoS (~3.3% for everyone, regardless of how much they stake) In that sense, Ethereum is way more equitable than Bitcoin.
There are also layer 2s which make transactions less than 10 cents, and will be even less with the client updates around September this year.
There is no power in validation. Proof of stake requires people who stake to authenticate perfectly, or they lose a portion of their stake. You lose nothing from relying on a Proof of Stake network.
>Do gas fees, long transactions times, and global gas wars still plague the ecosystem? If so, the assertion that it is "more useful than physical cash" seems just absolutely hilarious
What is this "global gas wars" you refer to?
Gas fees are quite low compared to international wire transfer fees, and that's ignoring new scalability technologies like zkRollups that reduce those fees more order(s) of magnitude. And unlike money held by a third party custodian like a bank or PayPal/Venmo, you don't have to worry about your account being frozen.
And unlike with physical cash, you can can transfer it digitally across the planet.
The transaction time is consistently 12 seconds since Ethereum moved to PoS. Ethereum doesn't have the issues of 10 minute block times that Bitcoin has.
Your criticism is uninformed.
