Only for now, because the minimum is 32 ETH to solo stake. Even then, people can run Rocket Pool minipools with 8 ETH and eventually, it’ll go down even more. And if you still don’t have enough, you can just buy rETH so you get block rewards and MEV.

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.
