Question for small and mid-size operators: how are you actually making the curta

[Raul Tejedor]

At today's hashprice (~$32/PH/day), an S19j Pro at 3.05 kW breaks even near $0.044/kWh. An S21 gets you to about $0.075. Depending on your tariff, that can mean only a handful of hours a day are genuinely worth running — and running through the rest isn't just low-margin, it's actively burning money.

The large operators have this solved. They have real-time price feeds, demand-response contracts, and someone whose job is watching the curve. What I'm curious about is everyone below that tier.

If you're running somewhere between 10 and a few hundred machines:

1. Do you curtail at all, or run flat and accept the average?
2. If you curtail, what triggers it — a fixed hour schedule, a price threshold you picked, an actual break-even calculation, or a judgement call?
3. Do you subtract the mining revenue you *lose* while paused when you evaluate whether curtailing was worth it? I suspect a lot of people count the electricity saved and stop there, which overstates the benefit.
4. Separately: how do you find out a hashboard is dying? Temperature alarm, pool dashboard, or do you find out when it's already gone?

Asking partly out of genuine curiosity about how this is done in practice, and partly because I'm building an open-source tool in this space and I'd rather learn what operators actually need than guess. Full disclosure so it doesn't look like I'm hiding it — MIT licensed, runs on your own network, link's in my profile rather than here because I want the answers more than the clicks.

The thing I keep coming back to: at a 20% unprofitable rate across the network, the gap between operators isn't always the power contract. Sometimes it's just whether anyone is doing the arithmetic.

Hmm, old generation ASICs are under a lot of pressure as hashprice drops after halving.

But if you decide only by looking at hourly profitability then it won't work. If you continue to mine temporarily low-margin with future BTC price appreciation and long-term strategy in mind, I don't think it will be much of a problem. Mining is not just about today's cash flow. It is also a future BTC accumulation strategy.

But yes, if your electricity cost is high then running your inefficient machine often mean just creating losses.

I think biggest difference here is scale. Large operator don't just use better software. They also have much better financing and energy market access.

If a small miner use same monitoring tool but pays $0.10/kWh of electricity, it will be difficult to compete with an industrial miner who gets $0.04/kWh of power.

If you are a small or medium miner then the biggest opportunity for you is automation and transparency. You may not have enterprise-level resource but you can reduce a lot of unnecessary losses with basic data analysis

1. Do you curtail at all, or run flat and accept the average?

Actually, this answer is not same for everyone. If you have cheap stranded energy or fixed low cost contract ten running 24/7 is definitely not illogical for you.

But if you operate under variable electricity pricing then curtailment is important for you. This is because mining load adjust to changes in electricity cost and hashprice. Meaning miner are gradually becoming more responsive to energy market signal.

However, manual curtailment is often not practical if you are small miner. You may be more profitable if you have an automated trigger system.
