Bitcoin just crossed a pretty significant threshold - we're looking at over 20 million BTC now in circulation. That's roughly 95% of all the bitcoin that will ever exist already out there. Worth pausing on that for a second.

What's interesting to me is how this plays out on the market supply curve. Satoshi locked in 21 million as the hard cap, and that number has always been the backbone of Bitcoin's credibility. Unlike fiat currencies that central banks can just print more of, Bitcoin's supply is completely transparent and immutable. You can't game it, can't change it, can't negotiate with it.

The halvings have done their job - they've been cutting miner rewards roughly every four years, pushing inflation down below 1%. Right now we're seeing about 450 BTC mined daily. At this pace, 99% of the total supply hits circulation by January 2035. But here's the kicker - the final million coins? That's going to take over a century to mine. We're talking 2105 before the last full bitcoin is issued, with fractional satoshis continuing until around 2140.

For anyone watching the market supply curve closely, this is where things get really interesting. New supply is basically drying up. The halvings mean fewer coins entering circulation, so we're approaching a point where scarcity becomes the dominant narrative. Miners are already starting to shift their thinking - once the block rewards essentially disappear, they'll be living entirely on transaction fees. That's a fundamental change to network economics.

The comparison to gold or oil only goes so far. With commodities, higher prices can trigger more production or new discoveries. Bitcoin can't do that. The supply curve is locked in place. As blockchain adoption scales and more people understand what this actually means, I think we'll see the scarcity story become even more central to how the market prices Bitcoin.

Interesting timing too - Bhutan apparently sold off most of its Bitcoin holdings recently, which is a different kind of supply pressure. But the underlying story here is about Bitcoin's long-term economics settling into a new phase where scarcity is the primary value driver rather than new issuance.
