Share a cold piece of knowledge about Bitcoin mining
Don't be fooled anymore, Bitcoin can actually never be fully mined!
Many people think that the total supply of Bitcoin is 21 million coins, and one day it will be 'mined out'.
Wrong! Bitcoin can never be fully mined.
Once I explain it, 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 infinitely decreasing geometric series — it keeps decreasing, keeps being mined, but will never reach 'absolute 0'.
Mathematically, it will get infinitely close to 21 million coins, but will never actually reach 21 million.
It's like a glass of water; every time you pour out half, you'll never pour it completely clean.
Moreover, when it gets to the end, the smallest unit of Bitcoin is 'Satoshi' (0.00000001 BTC).
Once the reward drops to 1 Satoshi, trying to halve it again won't work — thus the reward will approach zero but will never truly reach zero.
Feel the timeline:
By 2140, the additional output will be almost negligible, but there will still be that 'drop of water in the ocean'.
Some people ask: with the rewards nearly gone, what will miners mine?
The answer is simple: transaction fees.
In 2025, there was already an independent miner with a single block revenue of 3.147 BTC (approximately $350,000 at the time),
relying on the 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 have the motivation, mining won't stop, and the new supply will continue to exist in a 'toothpaste squeezing' manner.
Currently, 19,680,000 coins+ have been mined, with less than 1,300,000 coins remaining.
The later it gets, the slower the new additions, but it will never truly reach 21 million.
This is also why the scarcity of Bitcoin will continue to strengthen, and high prices are a fate written by mathematics.
