比特幣採礦環境影響：比特幣礦工如何挖掘比特幣？

根據個人或首席執行官的不同，比特幣採礦及其環境影響是自原子彈以來的不存在或最有害的事物。

Bitcoin's environmental impact has been a subject of heated debate, especially as the cryptocurrency market continues to boom.

比特幣的環境影響一直是激烈辯論的主題，尤其是當加密貨幣市場繼續蓬勃發展時。

Elon Musk, a known figure in the crypto sphere, has openly discussed his stance on BTC and other cryptocurrencies. For instance, in 2021, Musk announced that Tesla would no longer be accepting Bitcoin payments for its electric vehicles due to the environmental concerns associated with the cryptocurrency's mining activities.

埃隆·馬斯克（Elon Musk）是加密貨幣領域的知名人物，他公開討論了他對BTC和其他加密貨幣的立場。例如，在2021年，馬斯克宣布，由於與加密貨幣的採礦活動有關的環境問題，特斯拉將不再接受其電動汽車的比特幣支付。

This statement from the billionaire CEO sparked a discussion about the cryptocurrency's energy footprint and whether it was optimal to use the token.

億萬富翁首席執行官的這一說法引發了關於加密貨幣的能量足跡以及使用令牌是否最佳的討論。

Why Does Bitcoin Need Mining?

為什麼比特幣需要採礦？

Bitcoin is a cryptocurrency that runs on a distributed ledger technology called blockchain. In essence, it's a record of every transaction that is performed with Bitcoin, and it's open for anyone to view.

比特幣是一種加密貨幣，在稱為區塊鏈的分佈式分類帳技術上運行。從本質上講，這是使用比特幣執行的每筆交易的記錄，任何人都可以查看。

Miners act as gatekeepers, confirming these transactions and ultimately securing the system. The term "miner" might be a bit of a misnomer; they are more like accountants for the blockchain.

礦工充當守門人，確認這些交易並最終確保系統。 “礦工”一詞可能有些錯誤。他們更像是區塊鏈的會計師。

Miners use specialized hardware, known as ASIC miners, to solve complex mathematical problems in order to add new blocks of transactions to the Bitcoin blockchain.

礦工使用專門的硬件（稱為ASIC礦工）來解決複雜的數學問題，以便在比特幣區塊鏈中添加新的交易塊。

When miners verify 1MB worth of transactions, they are rewarded with Bitcoin for their work. This serves as an incentive for miners to continue securing the network and processing transactions.

當礦工驗證價值1MB的交易時，他們的工作將獲得比特幣的獎勵。這是礦工繼續確保網絡和處理交易的動力。

Bitcoin operates on a system of verification, not trust. Miners don't personally know each other, but this isn't necessary for the system to function. As long as the incentives are in place, the network continues to be maintained.

比特幣在驗證系統上運行，而不是信任。礦工不親自認識彼此，但這對於系統起作用並不是必需的。只要激勵措施就位，網絡就可以繼續保持。

With a maximum limit of 21 million coins, 19.9 million Bitcoin are already in circulation. The reward for miners, currently at 3.125 BTC, is halved every four years and is set to decrease again in 2028.

最高限額為2100萬枚硬幣，已經流通了1,990萬比特幣。目前為3.125 BTC的礦工的獎勵每四年減半，並將在2028年再次減少。

Is Bitcoin Mining Profitable in 2023?

比特幣開採在2023年是否有利可圖？

According to the Bitcoin Energy Consumption Index by the Digiconomist, a single Bitcoin transaction consumes an average of 1252 kWh of electricity, which is roughly the same energy used by an average American household over 53 days.

根據數字學家的比特幣能源消耗指數，單個比特幣交易平均消耗了1252 kWh的電力，這大致與美國普通家庭在53天內使用的能量大致相同。

In terms of carbon emissions, a single Bitcoin transaction generates about 668 kg of CO2, which is comparable to the emissions from a round-trip flight between London, UK, and New York City in the US.

就碳排放而言，單個比特幣交易產生了約668千克的二氧化碳，這與倫敦，英國，英國和美國紐約市之間的往返飛行的排放相當。

To put this into perspective, a single Bitcoin transaction has about the same carbon footprint as 842,000 Visa transactions or 51,210 hours of streaming YouTube.

為了介紹這一點，單個比特幣交易與842,000簽證交易或流式流式YouTube的碳足跡大致相同。

This begs the question again: Is any of this worth it, or should we scale down a bit on all the Bitcoin mining? Bitcoin is an unprecedented global network of money that has no single source of control. The more miners there are in a network, the more decentralized it is.

這再次引出了一個問題：這是否值得，還是我們應該在所有比特幣開採上縮小一點？比特幣是一個前所未有的全球貨幣網絡，沒有單一的控制來源。網絡中的礦工越多，它的分散程度就越多。

Even then the alleged energy consumption for Bitcoin is hyperbolic at best.

即使那樣，所謂的比特幣能源消耗充其量還是雙曲線。

Bitcoin's proof of work system is what allows it to function; furthermore, it enables Bitcoin's best feature, decentralization, to work without a hitch. If functional decentralized money is important to you, then Bitcoin is worth it.

比特幣的工作證明是使其運行的原因。此外，它可以使比特幣的最佳功能（權力下放）無需搭便車。如果功能分散的錢對您很重要，那麼比特幣值得。

What Energy Sources Are Used For Bitcoin Mining?

比特幣採礦使用了哪些能源？

Earlier this year, ARKK Investment's founder, Cathie Wood, made some interesting points about Elon Musk's assertions regarding Bitcoin mining being bad for the environment.

今年早些時候，ARKK Investment的創始人Cathie Wood關於埃隆·馬斯克（Elon Musk）關於比特幣採礦對環境不利的主張提出了一些有趣的觀點。

"The one thing that has changed here is the environmental concerns around Bitcoin, which have caused people like Elon Musk to pull away from it. But we believe even this is going to change, because, first of all, the percentage of Bitcoin mined with renewables and hydroelectric power is quite substantial. In China, I believe it's over 50%."

“這裡發生了變化的一件事是比特幣周圍的環境問題，這導致像埃隆·馬斯克這樣的人脫離了它。但是我們相信這甚至會改變，因為首先，首先，用可再生能源和水力發電的比特幣的百分比很大。在中國，我相信它超過50％。”

She went on to add that miners adopt green energy because they go to the locations where power is cheapest, and ultimately, cheaper power leads to more profits for miners.

她繼續補充說，礦工會採用綠色能源，因為他們去了最便宜的地方，最終，更便宜的電力為礦工帶來了更多的利潤。

Despite this, the claims about Bitcoin's environmental impact are often overstated, and it's crucial to consider the broader context. It's also worth noting that new cryptocurrencies with smaller environmental footprints are being developed every day, and Bitcoin is just one cryptocurrency among many.

儘管如此，關於比特幣環境影響的說法通常被誇大了，考慮更廣泛的背景至關重要。還值得注意的是，每天都會開發具有較小環境足蹟的新加密貨幣，而比特幣只是許多加密貨幣。
