Ask HN: Cryptocurrency naturally pegged to cost of hashing

Price volatility is a major obstacle to cryptocurrency adoption.

Here's a solution: set the mining reward equal to the expected hash count for mining a block. The value of the coin will naturally gravitate to the cost of computing one hash.

Why hasn't this been implemented yet? My best guess is that the Ponzi-scheme-like nature of most cryptocurrencies is a "feature." Most crypto enthusiasts are in it to make a quick buck, not for ideological reasons.

Where can I find a community of crypto-idealists to start building the decentralized utopia of the future?
