Perhaps there's already an alternative out there somewhere which is actually useful and not based on avarice, fraud, unsustainable resource usage, or unsustainable hype

The USD... /jk 🤣🤣

No currency or money system can avoid those, they are intrinsic features of capitalism, which is an intrinsic consequence of "whoever hoards more X, gets more of most things in life".

And can you blame people for wanting to hide their cards when hoarding X? Have you tried consulting real-time stock values, with market depth, and a list of market orders? Have you checked the pricing plans for a Bloomberg terminal?

Crypto is a world of transparency and freedom, compared to non-crypro markets.
