### Bitcoin Supply Cap and Scarcity
Bitcoin's finite supply and the [[Bitcoin Halving]] together create the disinflationary asset on the Bitcoin blockchain. By design, there will only ever be 21 million to exist, and so it is very likely the most scarce asset in modern history. It should then be noted it will take until about year 2140 for all Bitcoin to be mined. Very likely, no one on this planet today will be alive to see it.
Over 19 out of 21 million Bitcoin have been mined, so approximately 99% of the Bitcoin supply will have been mined _around_ year 2030. Wildly, the last 1% will take over a century to mine. It has, however, been estimated by blockchain intelligence firm [Chainalysis](https://www.chainalysis.com/) that [roughly 20% of the mined Bitcoin is lost](https://blog.chainalysis.com/reports/bitcoin-market-data-exchanges-trading/), making Bitcoin even more scarce. Taking this estimation as fact, the true final supply of Bitcoin around year 2140 would be ~ 17.2 million.

>To demonstrate the scarcity of Bitcoin at a global scale, let's assume 17.2 million Bitcoin has been mined (as circulating supply), and then let's split all those Satoshis equally amongst a world population of 7.7 billion. Everyone on the planet's equal share would be ~223,376.62 Satoshis, or .00223376 BTC. This would be worth about $89.35 USD at a $40k USD/BTC exchange rate.
### Satoshis and Bitcoin Divisibility
While some people suggest that Bitcoin is "infinitely divisible", this is an inaccurate characterization. Bitcoin is highly divisible, and it can be split into one hundred millionths (100 million Satoshis to 1 Bitcoin). This unit of measurement has been affectionately named a Satoshi after its infamous and anonymous creator.
