Many people have been deceived: Bitcoin can never be fully mined.

You must have heard this saying:

👉 "The total amount of Bitcoin is 21 million coins, and it will eventually be mined out."

Wrong.

In a mathematical sense, Bitcoin will never be 'fully mined'. You'll understand once I'm done explaining.

⛏️ The 'dead rule' set by Satoshi Nakamoto

Every 210,000 blocks, the block reward halves:

2009: 50 BTC

2012: 25 BTC

2016: 12.5 BTC

2020: 6.25 BTC

2024: 3.125 BTC

From then on: it keeps decreasing, keeps decreasing……

This is an infinitely decreasing geometric series.

Mathematically:

👉 It approaches 21 million infinitely, but will never reach 21 million.

It's like a glass of water; every time you pour out half,

you will never pour it all out.

🧮 Why won't it 'go to zero'?

The smallest unit of Bitcoin is 1 Satoshi = 0.00000001 BTC

When the reward decreases to 1 Satoshi, it cannot be reduced any further.

So the result is:

The reward approaches 0, but will never truly equal 0.

⏳ Time stretched to the limit

By the year 2140:

New production will be negligible,

but on paper—it's still not 21 million. Currently mined: 19,680,000+

Less than 1.3 million coins remain,

and the further we go, the slower it gets.

❓ What will miners rely on to make money in the future?

There is only one answer: transaction fees.

By 2025, it has already appeared:

🧾 Single block income 3.147 BTC

It's not about the rewards, but the skyrocketing transaction fees.

As long as someone uses Bitcoin for transactions:

✔️ Miners will have income

✔️ The network can operate

✔️ Mining will not stop

🧠 The truly terrifying part is this

The scarcity of Bitcoin

is not written by consensus,

is not chanted as a slogan,

but is written in a mathematical formula.

👉 New supply will always exist

👉 But the speed approaches zero infinitely

This is also why:

The 'scarcity' of Bitcoin will become harsher year by year.

Do you understand now?

21 million is not the 'endpoint',

but an ultimate value that can never be reached.
