Honest and simple coins.

Good evening. I'm looking for coins that are decentralized, simple and ecological.

I want to avoid:

1. Energy wasting proof of work like Bitcoin and Litecoin
2. Companies, CEOs and shady organizations like Ripple and BNB
3. Vaporware use cases, smart contracts, Tokens, etc. Like Ethereum and Solana.
4. With as few gimmicks as possible.

I am only interested in two use cases: buying it and holding it and using it to make cheap fast transfers.

Please give me your recommendations. Thank you in advance.
