Bitcoin Scarcity Explained

Bitcoin has a fixed maximum supply of 21 million coins — and over 19.6 million have already been mined. That leaves fewer than 1.4 million BTC still available… ever. No more will be created, no matter what.

Now picture 50 million Cash App users trying to buy just $10 worth of Bitcoin each week. If they all started today, they'd be fighting over the same final 1.4 million coins. The result?

1,400,000 ÷ 50,000,000 = 0.028 BTC per person
That’s just 2,800,000 sats — or less than 0.0005% of the entire supply.

Over a 4-year accumulation period, that $10 per week adds up to $2,080 — but how much Bitcoin would that actually get you, depending on the price and market conditions?

This calculator helps you visualize your Bitcoin accumulation over time.

Just enter your weekly savings amount, and the calculator will show you what kind of Bitcoin stack you could build in 4 years, before the supply dries up.
