Well, its not called interest, its called 'staking rewards'. You can also earn interest lending out your ETH, but that's a different process and entails counterparty risk.
Documentary is about concussions, I saw it years ago. Has nothing to do with the player's preference for chiropractic.
Player likes chiropractic because he believes it makes him perform more optimally, you inserted/made up this concept of the NFL pushing chiro to save money "at the player's expense".
Pro-athletes preferring chiro is a strong counter-signal these "skeptic" articles.
You're just making things up. It's not "at the expense of the player" These players are in peak physical fitness. If they want to go to any kind of doctor they can as they have medical insurance and they are all multi-millionaires.
Bitcoin makes no claim of being an income-producing asset.
All non-income producing assets { gold, wine, art, baseball cards, air-jordans } are bought as a store-of-value with the hope of selling it at a higher price.

There's a gold rush to accumulate ETH for staking reward payouts, and there is a new fee burn mechanism that will make ETH more scarce than BTC on a production basis. Demand for ETH seems to also be driven by DeFi products, NFTs and huge enthusiasm for the upgrade to PoS (July/Aug).
I don't have an ETH position, but this is my understanding of price action.
More institutions are buying homes and competing with the homeowners, because bonds are very-low yield and the stock market overpriced in terms of P/E.
