在-Home Bitcoin Mining To Secure The Network

一個在-home bitcoin miner describes his setup, offsetting heat costs, tax incentives and his role in securing the Bitcoin 網絡。

這件作品是 系列的一部分 that features interviews withBitcoin miners about their experiences setting up and scaling mining operations, as well as their views on the direction of the mining world. If you are mining Bitcoin and want to share your knowledge and story — the ups, downs and innovations – reach out to the author on Twitter @CaptainSiddH.

我有機會與礦業界最樂於助人的平民之一 Dan 坐下來，他是幕後黑手 @DaddyBTC_pleb, to dig into how he is heating his home with ASICs. He has shared several of his projects on Twitter, from a space heater enclosure to quiet fans that allow an unboxed S9 to heat a room. Dan also shared some numbers around savings in his natural gas bill to give you an idea for how much his system is saving him.

Hey Dan, thank you for coming on with me to chat about your home mining activities. You are sharing a ton of your experiments and setups on Twitter. What is your background, and how did you first become interested in Bitcoin and mining? 

所以，我實際上是一名醫生，我有四個孩子。 我在 2006 年完成培訓時開始投資。 那時，我正在投資股票並進行一些期權交易。 從那時起，我經歷了兩次重大的金融動盪：2007 年至 2009 年的整個時期以及 2020 年 2007 月大流行開始時的恐慌。 兩次我都對金融市場上的事情並沒有按照他們應該的方式發生的事實感到震驚。 例如，在 2008 年至 XNUMX 年底部跌落時，政府介入並阻止了系統分崩離析。 沒有人希望系統分崩離析，但坦率地說，那時候它就應該分崩離析，我寄希望於這個事實。

特別是有一次，我在貝爾斯登的看跌期權上投入了相當多的資金。 這些看跌期權（一種期權交易）是對股票價值下跌的賭注。 當時，我在一個交易小組，我們小組的所有人基本上都認為貝爾斯登將歸零。 好吧，這段時間我和妻子去海島度假，我們坐在沙灘上，防曬霜用完了。 我跑回房間去拿防曬霜，然後迅速登錄我的 E*TRADE 賬戶查看情況，我的看跌期權基本上被完全清空了。

我不知道到底發生了什麼。 事實證明，這一天美聯儲沒有計劃採取任何行動，但它將利率降低了大約 75 個基點，市場暴漲，貝爾斯登也隨之上漲。 最終，貝爾斯登確實跌至零，我能夠分三步退出交易，整體收支平衡，但那件事讓我口齒不清，因為政府介入以阻止這種需要發生的蔓延. 金融市場需要放鬆。 那時，我知道投資遊戲的競爭環境不再公平。

那次經歷和其他幾次經歷使我轉向了一種非常保守的模式——投資於派息股票。 在過去的十年裡，我一直在關注支付股息的股票和 DRIPs，它們是股息再投資計劃。 但是當大流行病襲來，市場陷入困境時，我覺得這將再次成為大蕭條。 我的交易小組中的幾個人正在討論投資和主要持有現金的方法。 然後政府再次介入，向經濟投入了 5 萬億美元。 我的意思是，在那之前你到底什麼時候聽說過“萬億”這個詞？ 我從沒幹過。

The conversation went from billions to trillions in a split second. The market came roaring back and there was just nothing that I wanted to buy. Everything seemed so overvalued in the stock market. So — to get to Bitcoin — at the end of 2020, I was on a trail run with a buddy of mine and the conversation turned to investments. I literally spent the last six miles of the 10-mile run explaining to my friend why he was a complete idiot for starting to invest in bitcoin. I repeated all the typical FUD I thought I knew about Bitcoin. And to be clear, the first time I heard about Bitcoin was around 2012, but I never investigated it.

After that run, I started paying more attention to the bitcoin market. I watched it run up to $40,000 before pulling back, and somewhere in that time I listened to a couple of podcasts. I have to give a big shout out to Preston Pysh and Peter McCormack. As soon as I heard that there was only ever going to be 21 million bitcoin, the light bulb switched on. That’s a perfectly scarce asset — nobody can mess with the monetary policy. It just started to make sense to me, and I felt confident enough to start investing in it.

I watched my investment double, but I also spent hundreds and hundreds of hours listening to podcasts, reading books, and going down the rabbit hole. At first, I saw it as a very unique alternative investment, but as I got more and more educated, it became so much more than that. I never had an interest in monetary policy or politics, so I never considered how our money is created and how that influences so many things in our lives. I never really cared about other places in the world that don't have access to “good money.” Shout out to Alex Gladstein for opening my eyes to the influence of Bitcoin 世界各地。

I started running my own node, and also took a look at mining. In April of last year, I priced some things out with Compass to do a package and I'm kicking myself because I didn't pull the trigger at that point. Miners were around $4,000 apiece. By July, I decided to go ahead and start purchasing miners — so now I have several that are going to come online through Compass but I also bought a couple of at-home 礦工。

So, you bought bitcoin, spun up a node, did your homework, fell down the rabbit hole — but what made you confident enough to purchase miners versus just taking that capital and buying more bitcoin with it? What kind of planning or aha moment went into you actually thinking “I want to mine this”?

As I went further and further down the rabbit hole, I started allocating more and more of my personal wealth to bitcoin. I have more than a little bit allocated to bitcoin, so I just felt like I needed to be Bitcoin. Running a node is part of that, but I wanted to go further to help further decentralization of the network. There is a centralization of hash power occurring — it's in Texas and the U.S. instead of China now, and while I’m thankful that there’s so much hash, it’s a weak point in my mind to have it in these huge mining centers.

數十萬 home miners out there make the network resilient. As I allocated more and more of my personal wealth to bitcoin, I felt obligated to be a part of that solution. Plus, it was interesting to me, and a way to acquire non-KYC bitcoin. Now, I pay taxes and do all the “right things” that I have to do and despite our government’s problems, I do believe in the United States of America, and I feel lucky to live here. However, I fear the possibility of another Executive Order 6102 to seize the gold. So, I want to know that I have some of my bitcoin wealth in non-KYC form. I still report what I mine on my taxes, but they don’t know my UTXOs.

所以，我從你的推文中知道你有多種機器，從 S9 到 S19。 你能告訴我們你是如何收購你的礦工的嗎？ 

First, I acquired two T19s through Compass — since those were the best machines I could find at the time for home mining. Once I ordered those machines, I hired an electrician to come out and install three 30-amp, 240-volt circuits to run these miners and give me some extra capacity.

後來，我發現了 五金市場 在 Telegram 上分組並從其中一位經過驗證的賣家處訂購了 S19 Pro。 對於所有這些新一代礦機，我進行了大量的金錢投資，雖然我想更多地了解它們的內部工作原理以適應它們，但我只是不想打開它們並弄亂它們，以免損壞某物。

為了進行一些試驗，我購買了三台 S9。 S9s 與 S19s 不同，有單獨的電源單元和你必須插入的電纜。設置這些對我來說是揭開神秘面紗的東西。 第二次我第一次啟動所有東西並且它正常工作時，我心想，“哇，這還不錯。”

然後我將它們拆解，清潔風扇，拉出電路板並用油漆刷刷掉它們，用壓縮空氣輕輕吹掉它們，然後將所有東西放回原處——一切正常。 這讓我感到更加自信。 因此，僅憑這一點，它就值回 S9 的價格。

I read you're heating your whole house with your miners. What does that system look like? 

所以首先，我在地下室的隔音盒中有一個 S19。 該箱子使用在線管道風扇主動通風，將空氣從箱子移動到過濾器和鼓風機之前的 HVAC 回風管。 我們將 HVAC 風扇保持在“開啟”位置，以確保較小的直列式管道風扇前方沒有壓力需要克服。 這樣做的結果是我們房子裡的空氣調節器不斷地排出不冷不熱的空氣。 這足以在較冷的月份保持房屋主層的舒適溫度。

對於兩個 T19，我做了一個更大的盒子，放在我們的閣樓上。 我用 XNUMX 英寸的管道通過兩種方式進行管道輸送：一種為我們的車庫供暖，另一種進入位於閣樓的樓上 HVAC 系統。 因此，這也將溫暖的空氣吹到了房子的二樓。

The S9s are all used as space heaters throughout the house. One is in the basement in my office, which is always the coldest room in the house. I used to run a 1,500-watt space heater but it would never keep the room at the right temperature, plus it would sometimes trip the circuit breaker. Now I'm running an S9 at 1,000 watts in a box, which is quieter than my old space heater while keeping the room totally comfortable. And it makes me money while it does it.

我的另一個 S9 在客廳裡，我最近做了一個 靜默建造 on. Our living room has a very high ceiling and above it is the attic, so when it's 20 degrees outside, you get this cold air seeping through the ceiling. I put the S9 in there as a space heater, and now that room stays nice and toasty.

丹的礦工大幅降低了他的天然氣用量和有效電費。

我想問一下那個無聲的構建——你僅僅通過更換風扇就成功地將 S9 降到了 60 分貝 (dB) 左右，對嗎？ 

Well, the S9 in my office is running at 1,000 watts inside a box with the fan at around 1,900 RPM, and it's quiet. So I wondered if I put “quiet fans” like the Noctua on the S9 maybe it would be quiet without the box at around the same RPM.

我從亞馬遜購買了風扇並安裝了一些適配器，需要用木鑿稍微修改一下。 然後我不得不用膠帶把它粘在一起。 一旦啟動並運行，它的安靜程度給我留下了深刻的印象。 最初，我在 1,000 伏電路上以 120 瓦的功率運行它，結果只有 60 分貝，但後來我將其降低到 900 瓦，現在得到大約 50 分貝，而不會過多地影響哈希率。 這種設置是任何大學生在宿舍裡都可以擁有的，坐在書架上，只是在冬天保持房間溫暖。

你們對礦機進行哪些維護？ 你定期清潔它們嗎？ 

With the S9s, I’ve pulled them apart and cleaned them before. I basically pull out the hash boards and brush them off gently with a paint brush, then blow them off with compressed air. I avoid vacuuming them because the vacuum builds up static electricity and I would hate to have that discharge on the circuit board. My environment is not very dusty and the air going into the machines is filtered, so I don’t have to clean them often — maybe every three months will be enough. I have not pulled apart the S19 and T19 units yet as they’re still under warranty.

在將您的設置設置到現在的位置時，您最大的痛點是什麼？ 

電氣要求很難弄清楚。 當我開始挖礦時，我什至不知道 PDU [配電裝置] 是什麼，也不知道如何理解參數——它們可以處理多少安培，你需要什麼樣的插頭，合適的電線。 所有這些事情對我來說都很難追查。 只是在礦工到我家之前的初步準備，比如告訴電工我需要什麼，花了很多時間研究和檢查這些技術性的東西，以確保我理解一切。

Cord lengths are a good example. I remember on the Bitmain site they indicate at some point that you want to keep your power cords less than 1.5 meters in length. I make sure my power cords are under four feet in length going from the PDU to the miner, but I don’t know what happens if I use longer cords. Could the cord heat up too much or create a fire risk if it’s too long? That information is just not available to the home miner without a technical background.

您是否從您的電力公司探索過任何電力購買協議以獲得更便宜的電價？ 

So, I did call my power company to tell them I am running server equipment for my business at home, and I would like to get a different rate. They said they don’t offer any incentives, however, when I dug further I found out if I had a separate meter, I could get what's called a small general service rate. That rate is about $0.05 per kilowatt hour, almost half my residential rate.

If I were to set up a separate meter on my property, it would have to be unattached to my house. The power company would consider that "new service” and they would run a circuit out to the shed for free, with up to an additional 350 amps of service. I'm debating that route, potentially with an immersion setup, but it depends how far down this rabbit hole I want to go.

您如何核算採礦活動的收入？ 您有公司實體還是個人收入？ 

I have an LLC. The beauty of that is you write off your expenses, you know, like my miner purchases. You can take full depreciation on those the first year or you can depreciate it over the course of three years. Then you write off your electricity cost as your business expense and so there's a lot of tax advantages to properly reporting this and it is very beneficial in terms of your bottom line.

對於正在考慮進入採礦業的人，您有什麼建議？ 他們應該去哪裡獲得更多信息和指導？

我認為 Telegram 群組——尤其是 home 採礦 one we are in — are really key. If you ask a question in there, you probably have three or four responses in a few minutes — and usually from somebody who's pretty knowledgeable.

我會跟隨 經濟煉金師 在 Twitter 上，因為他不斷發布有用的信息並轉發真正有用的內容。 “街頭採礦” was a really great article written a while ago by 分流器.

Overall, just do your homework. Don’t buy into the b.s. that mining at home is too difficult, mining at home is not profitable, you can't do it at your residential electrical rates. Unless you're in California and paying $0.40 per kilowatt hour, you're probably able to do it and be profitable. There are a lot of factors that go into it, but if you do your homework and research it ahead of time, you can figure out if it's worth it to you. Even if you’re only breaking even, it may be worth it to you in terms of getting non-KYC bitcoin or just helping to secure the network. That may be worth it to you. I know it was worth it to me.

感謝您與那裡的所有平民分享您的知識，丹。 你的修補是對許多人的啟發，包括我自己。
