Bitcoin follows a deflationary model, where its supply is systematically reduced through halvings.Every 4 years, the block reward for miners is cut in half, ensuring that the total supply never exceeds 21 million BTC—increasing its scarcity over time.
📜 Halving Timeline
🔹 Genesis Block (2009): 50 BTC per block 🔹 First Halving (2012): 25 BTC per block 🔹 Second Halving (2016): 12.5 BTC per block 🔹 Third Halving (2020): 6.25 BTC per block 🔹 Fourth Halving (2024): 3.125 BTC per block 🔹 Upcoming Fifth Halving (2028): 1.5625 BTC per block
This continues until 2140, when the final Bitcoin will be mined, and block rewards will reach zero.
📉 Impact of Halvings on Supply
Each halving reduces the rate of new Bitcoin entering circulation:
🔻 By 2028 → 1.5625 BTC per block 🔻 By 2040 → 0.1953125 BTC per block 🔻 By 2100 → 0.0000596 BTC per block
With every halving, Bitcoin becomes harder to obtain, making its supply increasingly scarce.
💰 Scarcity & Value
✔️ Only 21 million BTC will ever exist✔️ Over 90% of Bitcoin has already been mined (as of early 2025)✔️ Decreasing issuance leads to potential price appreciation due to limited supply & increasing demand
Bitcoin’s halving mechanism enforces scarcity, making it a unique store of value.This predictable, diminishing supply is why Bitcoin is often referred to as "digital gold."
