在-Home Bitcoin Mining To Secure The Network

一个在-home bitcoin miner describes his setup, offsetting heat costs, tax incentives and his role in securing the Bitcoin 网络。

这件作品是 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.

我有机会与采矿界最乐于助人的人之一丹（Dan）坐下来，他是幕后推手 @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，我实际上是一名医生，我有四个孩子。 2006 年，当我完成培训时，我开始投资。 那时，我正在投资股票并进行一些期权交易。 从那时起，我经历了两次大的金融动荡：从 2007 年到 2009 年的整个时期，以及 2020 年 2007 月大流行开始时的恐慌。 这两次我都对金融市场的事情并没有按照应有的方式发生这一事实感到震惊。 例如，在 2008 年至 XNUMX 年，当谷底退出时，政府介入并阻止了系统崩溃。 没有人希望这个系统分崩离析，但坦率地说，当时它应该已经崩溃了，而我正是依靠这一事实。

特别是有一次，我在贝尔斯登的看跌期权上赚了很多钱。 这些看跌期权（一种期权交易）是对股票价值下跌的押注。 当时，我在一个交易组里，我们组里的所有人基本上都认为贝尔斯登会归零。 好吧，我和我的妻子在此期间去岛上度假，我们坐在沙滩上，防晒霜用完了。 我跑回房间去拿防晒霜，然后迅速登录我的 E*TRADE 帐户查看情况，我的看跌期权基本上被完全清除了。

我无法弄清楚到底发生了什么。 事实证明，在这一天美联储没有计划采取任何行动，但它降低了大约 75 个基点的利率，市场暴涨，贝尔斯登也随之而来。 最终，贝尔斯登确实降到了零，我能够分三步退出交易，整体收支平衡，但那件事让我觉得很糟糕，因为政府正在介入以阻止这种需要发生的蔓延. 金融市场需要放松。 那时，我知道投资游戏的竞争环境不再公平。

那次经历和其他一些经历使我转向了一种非常保守的模式——投资于支付股息的股票。 在过去的十年里，我一直关注支付股息的股票和 DRIP，它们是股息再投资计划。 但是当大流行来袭，市场暴跌时，我觉得这将再次成为大萧条。 我的交易小组中的几个人正在讨论投资方法和主要保持现金。 然后政府再次介入，向经济投入了 5 万亿美元。 我的意思是，在那之前你什么时候听到过“万亿”这个词？ 我从没干过。

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 矿工。

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.

成千上万 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，我从你的推文中知道你有各种各样的机器，从 S9s 到 S19s。 你能告诉我们你是如何收购你的矿工的吗？ 

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.

后来，我发现了 硬件市场 在 Telegram 上进行群组，并从一位经过验证的卖家那里订购了 S19 Pro。 对于所有这些新一代矿工，我进行了大量的金钱投资，虽然我想更多地了解他们的内部运作以适应他们，但我只是不想打开它们并与它们混在一起，因为害怕破坏某物。

为了进行实验，我购买了三台 S9。 S9s 与 S19s 不同，具有单独的电源单元和必须插入的电缆。设置这些对我来说是神秘的。 当我第一次启动所有设备并且它正常工作时，我心想，“哇，这还不错。”

然后我把它们拆开，清理风扇，把板子拉出来，用油漆刷把它们刷掉，用压缩空气轻轻地把它们吹出来，然后把所有东西放回去——一切都奏效了。 这让我感到更加自信。 因此，仅此一项，就值 S9 的价格。

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

所以首先，我在地下室的隔音箱里有一个 S19。 该盒子使用直列管道风扇进行主动通风，以将空气从盒子移动到过滤器和鼓风机之前的 HVAC 的返回管道。 我们将 HVAC 风扇保持在“开启”位置，以确保较小的直列管道风扇无法克服前方的压力。 这样做的结果是，我们家里的空气调节器不断地散发出微温的空气。 这足以在较冷的月份保持房屋主层的舒适温度。

对于两个 T19，我建造了一个更大的盒子并将其放在我们的阁楼上。 我有两种用六英寸管道的管道：一种加热我们的车库，另一种进入阁楼上楼上的暖通空调系统。 所以，这也会把微温的空气吹到房子的二楼。

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.

我的另一台 S9 在客厅里，我最近做了一个 静默构建 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.

Dan 的矿工大大减少了他的天然气使用量和有效电费。

我想问一下那个静音结构——你仅仅通过更换风扇就成功地将 S9 降低到大约 60 分贝 (dB)，对吗？ 

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.

我从亚马逊购买了风扇并安装了一些适配器，需要用木凿进行一些修改。 然后我不得不用胶带把它粘在一起。 一旦我启动并运行它，我就对它的安静程度印象深刻。 最初，我在 1,000 伏的电路上以 120 瓦的功率运行它，只得到 60 分贝，但后来我把它降低到 900 瓦，现在在不影响哈希率的情况下得到大约 50 分贝。 这种设置是任何大学生都可以在他们的宿舍里，坐在书架上，让他们的房间在冬天保持温暖的东西。

您对矿机进行哪些维护？ 您是否定期清洁它们？ 

对于 S9，我之前已经将它们拆开并清洁过。 我基本上拉出算力板并用油漆刷轻轻刷掉它们，然后用压缩空气将它们吹掉。 我避免给它们吸尘，因为真空会产生静电，我不想让电路板上有这种放电。 我的环境不是很脏，进入机器的空气经过过滤，所以我不必经常清洁它们——也许每三个月就足够了。 我还没有拆开 S19 和 T19 装置，因为它们仍在保修期内。

将您的设置设置到现在的位置时，您最大的痛点是什么？ 

电气要求很难弄清楚。 当我开始采矿时，我什至不知道 PDU [配电单元] 是什么，也不知道如何理解参数——它们可以处理多少安培，你需要什么样的插头，合适的电线。 所有这些事情对我来说都很难追查。 只是在矿工到我家之前的初步准备工作，比如告诉电工我需要什么，就花了很多时间研究和检查这些技术问题，以确保我理解了一切。

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.

您是否曾与电力公司签订任何购电协议以获得更便宜的电费？ 

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.

您如何计算采矿活动的收入？ 您有公司实体还是这是个人收入？ 

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.

对于正在考虑进入采矿业的人，您有什么建议？ 他们应该去哪里获得更多信息和指导？

我认为 Telegram 群组——尤其是 home 采矿 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.

我会跟随 经济炼金师 在 Twitter 上，因为他不断发布好的信息并转发真正有用的东西。 “街头采矿” 是不久前写的一篇非常棒的文章 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.

感谢您与丹那里的所有平民分享您的知识。 你的修修补补是许多人的灵感，包括我自己。 

如果你想联系丹，他在推特上 @DaddyBTC_pleb. He shares his builds here as well as home mining projects from others. After our interview, Dan shared this incredible thread of tips on building your own enclosure for miners.
