比特幣接近供應上限：2100萬的限制會被取消嗎？

2024 年聖誕節前夕，比特幣達到了 1,980 萬個開採單位，實現了一個顯著的里程碑。這使得在達到 2,100 萬個總供應上限之前，剩下的比特幣只剩下不到 120 萬個可供開採。

Bitcoin's journey reached a remarkable milestone on Christmas Eve 2024, with 19.8 million BTC having been mined out of the total 21 million supply. This leaves less than 1.2 million bitcoins to be mined before the final batch is unlocked in 2140.

比特幣的旅程在 2024 年聖誕夜達到了一個非凡的里程碑，2,100 萬枚比特幣的總供應量中已開採出 1,980 萬枚。這使得在 2140 年最後一批比特幣解鎖之前，還有不到 120 萬枚比特幣可供開採。

After the 2024 halving, miners receive a reward of 3.25 BTC per block, which will continue until 2140 when the rewards become so small that they fall below a single satoshi. At that point, the emission of new bitcoins will effectively cease.

2024 年減半後，礦工將獲得每個區塊 3.25 BTC 的獎勵，這種獎勵將持續到 2140 年，屆時獎勵將變得非常少，以至於低於 1 聰。到那時，新比特幣的發行將有效停止。

Bitcoin's fixed supply, often hailed as a safeguard against inflation, is a key factor in its appeal to investors and traders. As the number of mined bitcoins nears its limit, the value of each unit could rise, driven by increasing demand and shrinking supply. However, the question of whether this fixed supply could be altered has recently sparked debate.

比特幣的固定供應通常被譽為抵禦通貨膨脹的保障，這是其吸引投資者和交易者的關鍵因素。隨著開採的比特幣數量接近極限，在需求增加和供應減少的推動下，每個單位的價值可能會上漲。然而，這種固定供應是否可以改變的問題最近引發了爭論。

In December 2024, BlackRock released an educational video on Bitcoin, discussing the possibility of removing the supply cap. While such a change is not impossible, it would require a significant shift in Bitcoin's protocol. Historically, the Bitcoin network has undergone hard forks to introduce changes, so it is technically feasible.

2024 年 12 月，貝萊德發布了一段關於比特幣的教育視頻，討論取消供應上限的可能性。雖然這種改變並非不可能，但它需要對比特幣協議進行重大轉變。從歷史上看，比特幣網路經歷過硬分叉來引入變化，因此在技術上是可行的。

However, many argue that altering the supply cap would fundamentally change Bitcoin's nature, transforming it into a different asset altogether. Critics believe that those who want an inflationary Bitcoin can simply use other cryptos, while supporters of the fixed supply view may continue to use Bitcoin in its original form.

然而，許多人認為改變供應上限將從根本上改變比特幣的性質，將其完全轉變為不同的資產。批評者認為，那些想要通膨比特幣的人可以簡單地使用其他加密貨幣，而固定供應觀點的支持者可能會繼續以原始形式使用比特幣。

Another fascinating aspect of Bitcoin is the concept of “virgin bitcoins.” These are coins that have never been used in a transaction and have a pristine transaction history. As the supply of new bitcoins dwindles, virgin bitcoins will become increasingly rare, adding an extra layer of value to these untouched coins. These bitcoins can only be obtained directly from miners through peer-to-peer transactions, further enhancing their rarity and desirability.

比特幣的另一個有趣的方面是「原始比特幣」的概念。這些是從未在交易中使用過且具有原始交易歷史的代幣。隨著新比特幣供應量的減少，原始比特幣將變得越來越稀有，從而為這些未受影響的硬幣增加了額外的價值。這些比特幣只能透過點對點交易直接從礦工那裡獲得，進一步增強了它們的稀有性和可取性。

At press time, Bitcoin is trading at $95,614.67 with a market cap of over $1.8 trillion. With a circulating supply of 19.8 million coins, the countdown to the final 1.2 million bitcoins has begun. However, as more bitcoins become lost or unspendable, the actual number in circulation will always be lower than the maximum supply, making the scarcity even more pronounced.

截至發稿時，比特幣交易價格為 95,614.67 美元，市值超過 1.8 兆美元。目前流通量為 1,980 萬枚，最終 120 萬枚比特幣的倒數計時已經開始。然而，隨著越來越多的比特幣遺失或無法使用，實際流通數量將始終低於最大供應量，使稀缺性更加明顯。
