USB比特幣礦工：比特幣挖礦的廉價介紹

對於想要進入比特幣挖礦世界的人來說，USB 比特幣礦機是一個簡單且經濟實惠的選擇。原則上，它們是一種即插即用的設備，幾乎不佔用任何空間，幾乎不需要任何電力即可運作。

People who want to enter the realm of Bitcoin mining have a simple and practical option with USB Bitcoin miners. They are essentially plug-and-play devices that take up very little room and need very little electricity to operate. In theory, this makes them a desirable option for those wishing to cheaply mine Bitcoin.

對於想要進入比特幣挖礦領域的人來說，USB 比特幣礦機是一個簡單實用的選擇。它們本質上是即插即用設備，佔用的空間很小，運作所需的電力也很少。從理論上講，這使得它們成為那些希望廉價開採比特幣的人的理想選擇。

However, they cannot compete with the effectiveness of the top Bitcoin miners, and even the best USB Bitcoin miners barely turn a profit.

然而，它們無法與頂級比特幣礦機的效率競爭，即使是最好的 USB 比特幣礦機也幾乎沒有盈利。

As a result, those hoping to profit from Bitcoin mining should avoid using USB miners. They are a cost-effective introduction to Bitcoin mining that enables beginners to grasp the fundamentals and use the more potent ASIC machines more effectively. Another option for experiencing Bitcoin mining on a budget is to use cloud mining platforms, which frequently provide new users with bonuses and special deals.

因此，那些希望從比特幣挖礦中獲利的人應該避免使用 USB 礦機。它們是對比特幣挖礦的經濟高效的介紹，使初學者能夠掌握基礎知識並更有效地使用更強大的 ASIC 機器。在預算內體驗比特幣挖礦的另一種選擇是使用雲端挖礦平台，該平台經常為新用戶提供獎金和特別優惠。

Sadly, the costs of running these gadgets exceed the possible revenues from using them. In fact, even if we disregard the cost of electricity, the Compac A1, the most potent USB miner on the market, would only mine about 0.00012775 BTC over the course of a year if we overclocked it to its maximum potential.

遺憾的是，運行這些小工具的成本超過了使用它們可能帶來的收入。事實上，即使我們忽略電力成本，市場上最強大的 USB 礦機 Compac A1 在我們將其超頻至其最大潛力的情況下，一年內也只能開採約 0.00012775 BTC。

This would only amount to a pitiful $8.70, indicating that at Bitcoin's present price, it would take nearly 30 years to recoup your investment. Hopefully, this helps you understand how unprofitable these gadgets really are. Even with our optimistic long-term Bitcoin price projection, these miners are best left as educational resources for those interested in learning about the mining process before purchasing a real Bitcoin miner.

這僅相當於可憐的 8.70 美元，這表明按照比特幣目前的價格，需要近 30 年才能收回投資。希望這可以幫助您了解這些小工具實際上是多麼無利可圖。即使我們對比特幣的長期價格預測持樂觀態度，這些礦機最好還是留給那些有興趣在購買真正的比特幣礦機之前了解挖礦過程的人作為教育資源。

Now that we've covered the fundamentals, let's examine our list of the top four USB Bitcoin miners for 2024.

現在我們已經介紹了基本原理，讓我們來看看 2024 年四大 USB 比特幣礦機的清單。

The GekkoScience Compac F is a compact USB miner that boasts a 400 GH/s hashrate and a low 10W power consumption, thanks to its AntMiner BM1397 ASIC chip. However, while it’s impressive for its size and can be overclocked for better performance, this miner, like most USB miners, won’t pay off your investment. The cost of electricity outweighs any potential earnings, making it more of a hobbyist tool than a profitable venture. Even with overclocking and a USB hub for expansion, the returns simply aren’t there to justify its use for serious mining.

GekkoScience Compac F 是一款緊湊型 USB 礦機，憑藉其 AntMiner BM1397 ASIC 晶片，擁有 400 GH/s 的算力和 10W 的低功耗。然而，雖然它的尺寸令人印象深刻，並且可以超頻以獲得更好的性能，但這款礦機與大多數 USB 礦機一樣，不會收回您的投資。電力成本超過了任何潛在收入，這使得它更像是一個業餘愛好者的工具，而不是一個有利可圖的企業。即使有超頻和用於擴展的 USB 集線器，回報也不足以證明其用於認真挖礦的合理性。

The NanoFury 2 boasts a hashrate of 5 GH/s, which seems almost pitiful in comparison to the Compac F, let alone a proper mining rig from Bitmain. However, its comparatively large heat sink, in combination with a cooling fan will likely keep the miner up and running for a long time.

NanoFury 2 擁有 5 GH/s 的算力，與 Compac F 相比似乎少得可憐，更不用說比特大陸的礦機了。然而，其相對較大的散熱器與冷卻風扇相結合可能會使礦機保持長時間運轉。

The Compac A1 builds on its predecessor with a higher hashrate of up to 500 GH/s when overclocked, using the powerful AntMiner BM13962 ASIC chip. However, despite this improvement, it falls into the same trap as other USB miners. Even with the increased power, the miner is far from profitable. It demands a dedicated USB hub and active cooling just to function optimally, which adds to the setup cost. Combining all this with a frankly outrageous price of $249, this USB miner has no real uses, as it’s too expensive to even be a learning tool.

Compac A1 以其前身為基礎，使用強大的 AntMiner BM13962 ASIC 晶片，超頻後哈希率高達 500 GH/s。然而，儘管有這樣的改進，它還是陷入了與其他 USB 礦機相同的陷阱。即使算力增加，礦工也遠未獲利。它需要專用的 USB 集線器和主動冷卻才能實現最佳功能，這會增加設定成本。將所有這些與 249 美元的坦率離譜的價格結合起來，這款 USB 礦機沒有任何實際用途，因為它太貴了，甚至無法作為學習工具。

The Lucky Miner LV03 is the cheapest USB Bitcoin miner available, but in terms of profitability, it’s also the worst one. Offering a low hashrate of 75 KH/s, this miner’s only purpose is to be a cheap learning tool for new Bitcoin miners. Don’t expect any real monetary value out of this one or any other USB miner for that matter.

Lucky Miner LV03是市面上最便宜的USB比特幣礦機，但就獲利能力而言，它也是最糟糕的。該礦機提供 75 KH/s 的低算力，其唯一目的是成為新比特幣礦機的廉價學習工具。不要指望這款或任何其他 USB 礦機能帶來任何真正的貨幣價值。

USB Bitcoin miners are not profitable at current Bitcoin and electricity prices. While they might serve as a good entry point for people looking to get into the world of Bitcoin mining, their price and hashrate don’t really give them any other use case. If you’re looking to make a profit, you should probably look into proper ASIC miners instead.

以目前的比特幣和電價來看，USB 比特幣礦機無法獲利。雖然它們可能是希望進入比特幣挖礦世界的人們的一個很好的切入點，但它們的價格和哈希率並沒有真正為他們提供任何其他用例。如果您想獲利，您可能應該考慮合適的 ASIC 礦機。

Another option for learning about Bitcoin mining is to use your GPU for the task. This is generally an unprofitable process, but the best GPUs for mining could give you a small profit, along with being able to play all of the best games.

了解比特幣挖礦的另一個選擇是使用 GPU 來完成任務。這通常是一個無利可圖的過程，但最好的挖礦 GPU 可以為你帶來少量利潤，同時也能玩所有最好的遊戲。
