Proof-of-Work and Proof-of-Stake mining is an exclusive club. Any alternatives?

[AndrewIdena]

Very few mining pools control the Bitcoin network in one area at great expense:
- 19 mining pools
- 3 pools control 51% of the hashrate
- 80% of the hashrate is in China
- $0.05 is breakeven cost per 1 KWh

Ethereum does not change the game:
- Initial wealth (70% is premint) is in a few hands: 53% is owned by 400 wallets.
- Mining is monopolized: 2 pools control 51% of the hashrate.
- Returns are miniscule: $0.3 daily earnings in PoS with 32 ETH min stake.

I am not allowed yet to post links, you can check btc and etherscan for stats.

Are there any alternatives?
