Interestingly, Bitcoin’s market cap is about 10% of gold’s ($2.1T vs. $21T), which seems to align with the attention-time idea.

If global population trends continue, this “attention share” could grow over time, maybe hitting 12.8% by 2030, 15.7% by 2035, and 18.4% by 2040

The growth rate of Bitcoin’s “Lindy value” would be around 5.5% per year, which is slower than certain trading strategies, but still meaningful.
