Bitcoin hard asset explained: scarcity, halving, and why it matters
Bitcoin has a hard-coded cap of 21 million coins that cannot be changed by any government or company. This makes it the only asset in history with a known, immutable maximum supply.
Every ~4 years the rate of new Bitcoin issuance halves. Supply growth decreases over time — the opposite of fiat currency.
No government, bank, or company can decide to "print more Bitcoin". The network is maintained by tens of thousands of independent nodes worldwide.

|---|---|---|---|
| Max Supply | 21M fixed | Unknown | Unlimited |
| Supply growth | Decreasing | ~2%/yr | Unlimited |
| Portability | Excellent | Poor | Good |

Bitcoinは2100万枚の固定供給量を持ち、世界中の誰も変更できません。プログラム可能な希少性です。
Practically impossible — any change to the 21M cap requires global consensus from nodes, miners, and users. It is the most protected parameter in Bitcoin.
Long-term yes — Bitcoin has outperformed inflation in all major currencies. Short-term it is volatile, best held as a long-term position.
