Bitcoin Mining Rigs Tested Across All Price Points: From Tens of Dollars to Professional ASICs

#Introduction

Over the past six years, I have tried almost every way to mine Bitcoin, from lottery miners costing tens of dollars to ASICs costing thousands of dollars, plus a $500 desktop computer. This article summarizes the real returns and risks of devices at various price tiers to help you decide whether they are worth the investment.

#1. Mining on a Regular Desktop PC: From Historical Myth to Real Returns

In November 2020, I bought $1,000 worth of Bitcoin at around $15,000 per coin and started mining on a regular desktop PC using the now-defunct Honey Miner software. PC users today can use the NiceHash QuickMiner program, while Mac users can use XM Rig. This type of software usually does not mine Bitcoin directly; instead, it uses your computer's CPU to perform proof-of-work for other cryptocurrencies, such as the privacy coin Monero, and then converts the earnings into BTC. Setting up the software and wallet takes about 45 minutes.

Six years ago, I mined on a regular desktop PC for a week and earned about $2.22, equivalent to 0.0012401 BTC, worth roughly $823 at current prices. That doesn't sound like much, but in Bitcoin's early days, an ordinary laptop could mine anywhere from 1 to over 50 BTC per day—in 2011, one person demonstrated that their regular gaming PC mined 1 BTC a day. Today, the growth in hashrate and multiple halvings have made mining on a regular computer nearly unprofitable.

#2. Lottery Miners: Low-Cost Devices and a Game of Probability

Lottery miners are plug-and-play devices: you plug them into a home outlet and connect a wallet, and they start running. Their principle differs from traditional pooled mining: normal miners join a mining pool and share rewards, while lottery miners independently try to solve an entire block in their own solo mining pool. If you guess correctly, you receive the full 3.125 BTC block reward, worth about $27,000.

I tested eight lottery miners priced around $70 each, plus five devices ranging from $250 to $800. A $70 unit with a hashrate of about 1.0 kH/s has a chance of solving a block of roughly 1 in 750 million per year, about 60 times less likely than winning the Powerball jackpot with a single ticket; in my test, it ultimately returned only about $4, making the roughly $560 total spent on the devices feel more like a novelty toy. By comparison, a $250 device with 2.4 Th/s has a hit probability of about 1 in 7,130 per year; a $500 device with 4.8 Th/s is about 1 in 3,565; and an $800 device with 9.6 Th/s is about 1 in 1,782, with annual electricity costs around $200. From an investment standpoint, this is not profitable, but over the past year, miners have still solved blocks using devices costing as little as $75, because cryptographic randomness does not favor higher hashrate.

#3. ASIC Miners: Real Returns After 3 Years and 4 Months

Three years and four months ago, I spent $5,000 on two ASIC S19 Pro 110 Th/s miners, hosted at a facility in Iowa with an electricity rate of 6.5 cents per kWh, which shut down this month. After running for 1,232 days, they mined a total of 0.23638 BTC, worth about $16,000 at current prices.

But that's not the whole profit picture. The machines depreciated by about $4,600 and now have almost no residual value. Electricity costs over 40 months totaled $11,424, or about $285.60 per month. The final net profit was only $20.89. If I had used that $5,000 to buy Bitcoin directly, even if the price fell from $120,000 to $65,000, I would still have made about $9,918 by holding the same amount of BTC without paying for electricity.

Bitcoin's price cycle also confirms this: it typically peaks about 500 days after a halving, then the bear market bottom appears within about 365 days. Current price swings are a normal correction in the long term.

#4. Altcoin Miners: Why "Mining Altcoins for BTC" Often Doesn't Work

I have also tried mining altcoins with dedicated miners and then converting them to Bitcoin. Most devices were only profitable for the first few months to a year; once the corresponding altcoin price dropped, both the device's profitability and used resale value collapsed. Based on current market conditions, here's what the numbers look like:

• Ice River KS1 (mining Kaspa): annual loss of about $450.
• Gold Shell KD Box 2 (mining Kadena): annual loss of about $3,222.68.
• AlphaPlex DG Home 1 (mining Dogecoin/Litecoin): annual loss of about $222.13.

These devices can now basically only be sold on the secondhand market. The market downturn may have amplified the losses: six to seven months ago, these mining strategies were still showing decent profits.

#5. Mining vs. Buying Bitcoin: When Mining Can Be More Profitable

Mining isn't always worse than buying Bitcoin directly. The following situations may improve returns:

• Taking advantage of tax benefits: for example, U.S. Section 179 allows you to fully write off the value of equipment from taxable income in the year of purchase.
• Buying mining machines at low prices during a bear market and selling them during a bull cycle.
• Using ASIC heat to warm a residential or commercial space, offsetting heating costs you would otherwise have to pay.
• Situations where rent includes free electricity.

For most people without these advantages, dollar-cost averaging (DCA) into Bitcoin is likely simpler and involves more manageable risk. If you just want to experience mining on a regular computer, I mined about 0.0080008 XMR over the past three days by running XM Rig on a Mac Mini, which converts to roughly $30, further proving that low-hashrate earnings are extremely low.

#Conclusion

Bitcoin mining devices at various price tiers each carry their own risks: low-cost lottery miners depend on extremely low probabilities; mid-range ASICs have payback periods affected by electricity costs, coin prices, and hashrate growth; and altcoin miners face asset decay. Unless you have advantages such as tax benefits, free heating, or very low electricity rates, directly buying Bitcoin on a regular schedule is more reliable.
