比特幣誕生 16 週年：公佈 2,100 萬比特幣供應上限

加密貨幣市場可能正處於動盪之中，但今天提供了一個停下來反思的理由。距離中本聰已經整整16年了

Cryptocurrency market may be in turmoil, but today marks a moment in history that deserves a pause and reflection. It has been exactly 16 years since Satoshi Nakamoto, Bitcoin's (BTC) enigmatic creator, unveiled what is arguably its most defining feature: the 21 million BTC supply cap.

加密貨幣市場可能正處於動盪之中，但今天標誌著一個值得暫停和反思的歷史時刻。距離比特幣 (BTC) 的神秘創造者中本聰 (Satoshi Nakamoto) 公佈可以說是其最具決定性的特徵：2100 萬個 BTC 的供應上限，已經整整 16 年了。

This moment in 2009 introduced the world to a system that would forever change perceptions of money. In the Bitcoin whitepaper, Nakamoto detailed a methodical and finite issuance process, ensuring that Bitcoin's total supply would never exceed 21 million BTC.

2009 年的這個時刻向世界介紹了一個將永遠改變人們對金錢的看法的系統。在比特幣白皮書中，中本聰詳細介紹了一套有條不紊且有限的發行流程，確保比特幣的總供應量永遠不會超過 2,100 萬個 BTC。

The coins will be distributed to network participants as rewards for validating transactions, with the issuance halving every four years. This carefully planned progression — 10.5 million coins in the first four years, halving to 5.25 million in the next and so on — is designed to taper off until the final Bitcoin is mined sometime around 2140.

這些代幣將作為驗證交易的獎勵分發給網路參與者，發行量每四年減半。這個精心規劃的進程——前四年生產 1,050 萬枚比特幣，接下來減半至 525 萬枚，依此類推——旨在逐漸減少，直到 2140 年左右開採出最終的比特幣。

Back then, Bitcoin had no price. It existed only as an idea, a digital experiment discussed among a small group of enthusiasts on forums and mailing lists. They engaged in technical discourse, delving into the intricacies of Bitcoin's architecture and marveling at its potential to revolutionize finance.

那時，比特幣沒有價格。它僅作為一個想法存在，是一小群愛好者在論壇和郵件列表上討論的數字實驗。他們參與技術討論，深入研究比特幣架構的複雜性，並驚嘆於它徹底改變金融的潛力。

Now, fast forward to today, and the concept Bitcoin introduced has evolved into a global asset, valued at nearly $2 trillion and woven into the fabric of conversations about finance, technology and economics. Among Bitcoin's most compelling traits is this very supply cap — unchanging and immutable — making it an outlier in a world of unlimited fiat currency printing.

現在，快進到今天，比特幣引入的概念已經發展成為一種全球資產，價值近 2 兆美元，並融入了有關金融、技術和經濟的對話結構。比特幣最引人注目的特徵之一就是這種供應上限——不變且一成不變——使其成為無限印刷法定貨幣的世界中的異類。

However, there is a divergence between the theoretical supply and the actual circulating amount. As Bitcoin's genesis block was being mined, Satoshi Nakamoto, who disappeared years ago, is believed to have also mined around one million BTC in the early days. These coins have never been moved and are considered lost to time.

但理論供應量與實際流通量有差距。當比特幣的創世塊被開採時，多年前失蹤的中本聰據信早期也開採了約 100 萬個比特幣。這些硬幣從未被移動過，被認為隨著時間的流逝而丟失。

Similarly, countless other early coins remain inaccessible in forgotten wallets or due to lost keys. While the ledger records approximately 19.8 million BTC in circulation today, the functional supply is almost certainly lower.

同樣，無數其他早期硬幣仍然無法在被遺忘的錢包中或由於丟失鑰匙而無法訪問。雖然帳本記錄目前流通的比特幣數量約為 1,980 萬，但功能供應幾乎肯定會較低。
