Sharing a little-known fact about Bitcoin mining‼️
Don’t be fooled anymore; Bitcoin can never be fully mined.
Many people think that the total supply of Bitcoin is 21 million coins and that one day it will be “mined out.”
Wrong! Bitcoin can never be fully mined.
Once I finish explaining, you'll understand
Because Satoshi Nakamoto designed a strict rule: the reward halves every 210,000 blocks.
2009: 50 coins → 2012: 25 coins → 2016: 12.5 coins → 2020: 6.25 coins → 2024: 3.125 coins……
This is an infinite decreasing geometric series — it keeps decreasing, keeps mining, but will never reach “absolute 0.”
Mathematically, it will approach 21 million coins infinitely but will never actually reach 21 million.
It’s like a glass of water; each time you pour half, you never completely fill it.
And in the end, the smallest unit of Bitcoin is “Satoshi” (0.00000001 BTC).
Once the reward drops to 1 Satoshi, halving can no longer occur — so the reward approaches zero but never truly reaches zero.
Here’s the timeline:
By around 2140, the new issuance will be almost negligible, but it will still be just a “drop in the ocean.”
Someone asked: If the rewards are almost gone, what do miners mine for?
The answer is simple: transaction fees.
In 2025, there have already been independent miners earning 3.147 BTC from a single block (about 350,000 USD at the time),
thanks to a surge in transaction fees.
In the future, miners’ main income will come from transaction fees, not block rewards.
As long as there is demand for Bitcoin transactions, miners will be motivated, and mining will never stop. The new supply will continue to be “squeezed out” gradually.
Currently, over 19.68 million Bitcoins have been mined, with less than 1.3 million remaining.
The rate of new issuance slows down over time, but it will never truly reach 21 million.
This is also why Bitcoin’s scarcity will only increase, and high prices are a fate written into its mathematical design.
