Every Bitcoin cycle follows the same emotional arc. Price surges, new miners flood in, hardware sells out, electricity bills feel like a bargain — and then the crash comes. BTC drops 40%, 50%, sometimes 70% from its peak. Crypto Twitter goes quiet. Mining profitability calculators turn red. And thousands of miners worldwide start asking the same question: should I turn this thing off?
If you're an Australian home miner, the answer is almost certainly more nuanced than a simple yes or no. Bear markets change the economics of mining dramatically, but they don't necessarily make it pointless. In fact, some of the best long-term mining positions are built during bear markets — if you understand what's actually happening under the hood and plan accordingly.
What Actually Changes When BTC Drops
When the Bitcoin price falls, the immediate impact on your miner is exactly zero. Your machine still hashes at the same rate. It still draws the same wattage. Your pool still sends you roughly the same number of sats per day (assuming difficulty hasn't adjusted yet). What changes is the fiat value of those sats — and that's where the pain starts.
Say you're running a Canaan Avalon Nano 3S at 6 TH/s and earning 800 sats per day. At $160,000 AUD per BTC, that's roughly $1.28 AUD. At $80,000 AUD per BTC, the same 800 sats is worth $0.64. Your electricity cost hasn't changed — it's still costing you around $1.00–$1.20/day to run at average Australian rates. The miner just went from marginally profitable to cash-flow negative in fiat terms, without a single setting changing on the machine itself.
This is the moment that separates miners who survive bear markets from those who don't. Because what happens next — difficulty adjustment — is the mechanism that makes mining self-correcting, and it's the reason bear markets are temporary pain for patient operators.
The Difficulty Adjustment: Mining's Built-In Relief Valve
Bitcoin's difficulty adjusts approximately every two weeks (2,016 blocks). When the price crashes, large-scale industrial miners — the ones paying for warehouse leases, staff, and debt servicing — start turning off their least efficient machines. As hashrate leaves the network, difficulty drops. When difficulty drops, the remaining miners earn more sats per unit of hashrate.
This is the single most important thing to understand about bear market mining: the network rewards those who stay on. If 30% of global hashrate shuts down and you keep your miner running, your share of the total block reward increases proportionally. You're earning more sats per day at exactly the point when those sats are cheapest. For anyone thinking about mining as a long-term DCA strategy, bear markets are when the accumulation accelerates.
Historically, this pattern has played out in every major cycle. The 2022 bear market saw Bitcoin mining difficulty drop roughly 7.3% at its steepest adjustment as miners capitulated. Home miners who kept their machines running through that period accumulated sats at what turned out to be generational lows.
Your Electricity Bill Doesn't Care About the BTC Price
This is the core tension of bear market mining in Australia. Electricity rates across the country range from roughly 25c/kWh on good plans to over 40c/kWh on default tariffs. Your power retailer doesn't offer a bear market discount. That means when BTC halves in price, your cost-to-revenue ratio doubles overnight.
For high-wattage machines, this can become genuinely unsustainable. An Antminer S21 at 2,643W costs roughly $17–$25 AUD per day to run depending on your rate. During a deep bear market, daily BTC revenue might drop below that figure, meaning you're paying more in electricity than the mined coins are worth at current prices. That's a critical distinction — at current prices. If you believe BTC will recover (and historically it always has), those "unprofitable" sats become extremely profitable in hindsight.
The key question isn't "am I profitable today?" It's "can I afford to keep paying this electricity bill for 6–18 months without needing to sell the coins I'm mining?" If the answer is no, you have a cash flow problem, not a mining problem.
Which Miners Survive and Which Don't
Bear markets are a stress test, and the machines with the worst efficiency ratios fail first. Efficiency is measured in joules per terahash (J/TH) for Bitcoin miners — the lower the number, the less electricity you spend per unit of work. When revenue drops, inefficient miners hit their shutdown price first.
Here's how the current lineup stacks up under pressure:
Most resilient: The Antminer S21 Pro at 15 J/TH has the best efficiency of any miner in our catalogue. It's the last machine you'd turn off, because it produces the most hashrate per watt. Similarly, the Antminer S21 at 17.5 J/TH and Avalon A1346 at 30 J/TH have efficiency figures that keep them viable deeper into a downturn than older hardware.
Most vulnerable: Older-generation machines like the Avalon A1246 at 38 J/TH, WhatsMiner M30S at ~36 J/TH, and M31S+ at 40 J/TH are the first candidates for shutdown when margins compress. They still hash, but the electricity cost per sat is significantly higher. Our S19K Pro vs S21 comparison and M30S vs M31S+ comparison break down these efficiency differences in detail.
Nearly immune: Ultra-low-power miners like the Bitaxe Gamma 602, Lucky Miner LV06, and Lucky Miner LV08 cost so little to run — often under $0.50/day — that bear market electricity maths barely registers. These solo miners keep hashing through anything because turning them off saves you almost nothing. The same logic applies to altcoin miners like the IceRiver KS0 Ultra at 100W and the Lucky Miner LG07 at 12W.
The Bear Market Playbook for Australian Home Miners
Surviving a downturn isn't complicated, but it does require planning before the crash, not during it. Here's the practical framework.
1. Know Your Shutdown Price
Calculate the BTC price at which your daily electricity cost exceeds your daily mining revenue. This is your break-even — or more accurately, your cash-flow break-even. Below this price, every day of mining costs you more in fiat than the coins are worth at spot. You can still choose to mine below this level (accumulating coins you expect to appreciate), but you need to fund that electricity from other income. Knowing the number removes the guesswork.
2. Reduce Your Electricity Cost
The single highest-leverage move in a bear market is lowering your power rate. Even a small reduction extends your break-even point significantly. Options include switching to a cheaper retailer, moving to a time-of-use plan and running only during off-peak hours, maximising solar self-consumption, or exploring battery and off-grid setups. The Australian electricity market guide covers how to shop for better rates in each state.
3. Downsize, Don't Quit
If you're running multiple machines and the electricity bill is becoming uncomfortable, don't shut everything down. Turn off the least efficient miner first and keep the best one running. A single Avalon Nano 3S drawing 140W keeps you in the game for about $1/day while maintaining your position in the network and your daily sat accumulation. Going from three miners to one is a rational response. Going from one miner to zero is an emotional one.
4. Underclock for Efficiency
Most ASIC miners can be underclocked to reduce power consumption at the expense of some hashrate. The efficiency gain is often non-linear — dropping your clock speed by 20% might only reduce hashrate by 15% but cut power draw by 30%. During bear markets, this trade-off is almost always worth it. Custom firmware like BraiinsOS+ and LuxOS makes underclocking straightforward on supported machines. Our guides on mining firmware and overclocking and underclocking cover the process.
5. Accumulate, Don't Liquidate
If you can afford to keep mining without selling the coins, a bear market is the best possible time to stack. You're earning more sats per TH (thanks to difficulty drops), buying those sats at depressed fiat values, and the historical pattern suggests they'll be worth significantly more in the next cycle. This is the DCA mining thesis in its purest form. The ATO still requires you to declare mined coins as income at the value received, but the upside is that your assessable income is lower during bear markets (because the coins are worth less when you receive them), and if you hold for 12+ months, you'll get the CGT discount on any future gains.
6. Use the Downtime to Maintain Your Hardware
Bear markets are the perfect time to service your machines. Clean dust from fans and heatsinks, check for worn fans or failing PSU capacitors, update firmware, and optimise your thermal management setup. A miner that's been properly maintained during the quiet period is ready to run at full capacity the moment conditions improve — while neglected machines often fail right when you need them most.
7. Consider Altcoin Diversification
Bitcoin bear markets don't always hit altcoins on the same timeline or with the same severity. Running a small altcoin miner alongside your BTC setup can provide diversified exposure. The IceRiver KS0 Ultra for Kaspa, Goldshell Mini Doge III for DOGE/LTC, or Goldshell AL BOX II Pro for Alephium are all low-power options that spread your risk across multiple networks and algorithms. Our altcoin vs Bitcoin mining comparison and best altcoin ASICs guide can help you evaluate the options.
What NOT to Do in a Bear Market
Don't panic-sell your hardware. Miner resale values drop during bear markets just like everything else. Selling a machine at the bottom of a cycle locks in your loss. If the hardware still works and you can afford to store it, waiting for the next cycle will almost always yield a better outcome — either through resumed mining or a better resale price.
Don't buy new top-tier hardware during the crash. This sounds counterintuitive, but the bull market mining trap has a bear market cousin: buying expensive new-gen machines at the bottom feels smart, but if the bear market drags on for another 12 months, you're servicing a large capital outlay with depressed returns. If you want to buy during a bear market, buy cheap, efficient entry-level machines with low operating costs.
Don't ignore your electricity plan. Many Australian power contracts roll over annually. If you set up your miner during a bull market and never checked your rate again, you might be paying 10–15c/kWh more than necessary. State-by-state rate differences are significant, and switching retailers takes 10 minutes online. In a bear market, those savings are the difference between staying on and shutting down.
Bear Markets End
Every Bitcoin bear market in history has been followed by a new all-time high. The 2014 crash, the 2018 crash, the 2022 crash — each felt like the end at the time, and each was followed by a recovery that made the previous peak look like a footnote. That doesn't mean the next one is guaranteed to follow the same pattern. But it does mean that miners who stayed on through previous downturns and held their accumulated coins came out dramatically ahead.
The miners who survive bear markets share three traits: low electricity costs, efficient hardware, and the conviction to keep accumulating when the charts look terrible. If you can manage all three, a bear market isn't a crisis — it's a sale on sats, and your miner is shopping for you every single day.
Build your bear-market-proof setup with low-power ASICs from our full range, and make sure your operation is optimised before the next downturn hits. The best time to prepare was yesterday. The second best time is now.
