Yup! Fixed cap, or scarcity, indeed, is one of the most important differences between BTC and fiat, which, as we can see for years, can be printed / added to the system with no limits. Similar case fits crypto projects based on PoS 🙈 But, let's not forget, that all 21M aren't actually available, it's much less to join. So day after day we should buy some. Stack sats, no laziness no excuses.
