Virtual Mining Farm: An ASIC Profitability Simulator

Why create a virtual mining farm?

When you invest in mining, it often starts simply. One ASIC, then two, then a newer, more powerful model — sometimes in another mining farm, with another hosting contract and therefore a different price per kWh. Gradually, your view fragments.

Many investors own several ASICs bought at different times from several hosting providers, so each machine has its own hosting conditions. The result: you don’t have a global view of your investment.

A virtual mining farm lets you aggregate your contracts, simulate, project and get a consolidated view. That’s exactly the purpose of the « My Farm » section of the Startmining simulator. It lets you:

• group all your contracts together
• virtually recreate your real operating conditions
• analyze the overall performance of your mining portfolio
• simulate changes and scenarios

In other words: you no longer look at an isolated ASIC. You manage your investment strategy.

In this tutorial, we’ll see how to create your virtual mining farm, add your existing hosting contracts, view the consolidated performance of your ASICs, and simulate your portfolio’s future evolution.

Step 1: Create your virtual farm

Go to the « My Farm » section of the simulator: pro.startmining.io/farms

Click « Create a farm. » At this stage, three configuration modes are offered:

• Startmining (recommended): an optimized, pre-set configuration
• Guided mode: a simplified assistant to get started
• Pro mode: full control over all parameters

In this article, we choose Pro mode. Why? Because we want to faithfully reproduce real operating conditions and get a professional result. Pro mode lets you manage several ASICs, precisely adjust the electricity price, set the fees (pool, hosting, uptime) and fine-tune each strategic variable (profit sharing, etc.). You can thus configure a mining farm in hosting precisely. This tool is suited to advanced investors.

The other modes are designed to suit all investor profiles, especially beginners or those who want a quick, simplified setup. But when it comes to managing a mining portfolio like a strategic investor, customization becomes essential.

Once Pro mode is selected, you can name your virtual mining farm. Its name can reflect a strategy (« Long term 2028 »), a machine type (« S21 ASIC portfolio »), or all your hosting contracts. You can also enter the price per kWh, the location and the hosting and pool fees. In our case, though, these parameters will be adjusted when integrating the ASICs into our farm, since we run machines under individual conditions.

Here you’re not simply creating a simulation. You’re structuring your portfolio. And this is where management becomes strategic, and where value is created.

Step 2: Add your ASICs and reproduce your real conditions

Once your farm is created, the next step is to add your machines. In the ASIC section, choose an ASIC from the catalog or a custom one.

The custom ASIC lets you set its power (hashrate) and consumption (watts) yourself — ideal if you’re among those who overclock or underclock their ASIC. Done? Click « advanced settings » to customize the ASIC’s conditions. You’ll now faithfully rebuild your hosting contract. For each machine, enter:

• the price per kWh in your contract
• the minimum uptime of your contract
• any fees (pool, hosting, maintenance, profit split, etc.)

The goal is simple: reproduce exactly the conditions in which your ASIC operates. The more precise the parameters, the more faithful the simulation will be to your economic reality. If you own several identical machines, you can group them. If your conditions differ from one farm to another (a different price per kWh), create a separate line with a new ASIC.

In our example, we added the following ASICs:

• S23 in premium hosting, 98% uptime, $0.075/kWh.
• S21 Pro in hosting at $0.055/kWh, 80% uptime.
• S21 Pro in hosting at $0.06/kWh, 85% uptime.

This is where the tool takes on its full strategic dimension: you no longer model an isolated machine, but reconstruct your mining portfolio as it really exists. Once all your ASICs are added, your virtual farm automatically generates consolidated indicators.

Step 3: View your farm’s overall performance

Once your ASICs are added, click « calculator. » Your virtual mining farm doesn’t just add up machines — it consolidates your strategy. You immediately get a global view of:

• your daily/monthly/yearly profit
• your consolidated APR
• your average Bitcoin production cost (OPEX)
• your total energy consumption (in kWh and MWh)

The perspective changes. Instead of looking at each hosting contract separately, you analyze your overall exposure. Maybe one ASIC is slightly in the red… but offset by a more efficient one. Maybe your average production cost and kWh price are more competitive than you thought. Or, on the contrary, your portfolio is too exposed to a high Bitcoin price to stay comfortable in a correction.

This consolidated view lets you identify weak points, measure your survival threshold and understand your real profitability. Your mining is no longer a series of isolated contracts — it becomes a manageable portfolio. And a manageable portfolio can be optimized.

Step 4: Simulate the future… and test your decisions

This is where the virtual farm shows its full power. Once your portfolio is modeled, you can change one key variable: the Bitcoin price. In seconds, you see the impact on your overall profit and your consolidated APR.

This means you can simulate your losses if Bitcoin’s price falls 10% below your production threshold. In our example, that would correspond to a Bitcoin price of around $37,000. You can also simulate a return to the ATH to analyze how your ROI and break-even evolve.

But the tool goes further. You can duplicate your farm in one click. Why is that strategic? Because it lets you test decisions before applying them in reality. For example:

• Remove an ASIC category (e.g., older, less efficient models)
• Simulate adding a new generation (better efficiency but a high purchase cost)
• Compare two strategies with equal capital
• Observe the impact on your average production cost

Imagine removing your least efficient machines. Does your average Bitcoin production cost fall? Does your energy exposure decrease? Does your profitability become more stable in a bear market? Instead of speculating… you measure. This ability to duplicate and compare turns the tool into a genuine strategy simulator. You no longer endure the market — you prepare your scenarios. And in mining, anticipating is often worth more than reacting.

Conclusion: from an isolated hosting contract to a mastered strategy

Mining is evolving. In 2026, it’s no longer simply about buying a machine and waiting. It’s about managing a portfolio of energy assets exposed to the Bitcoin price, the cost of electricity, network difficulty and market cycles. And like any portfolio, it requires a consolidated view.

The « My Farm » feature isn’t just for adding up ASICs. It lets you measure your average production cost, identify your weak points, test scenarios before investing, and arbitrate between holding, selling or upgrading. You no longer manage isolated contracts — you manage a strategy. Before adding a new ASIC, removing one, or changing your exposure: simulate!

Access your virtual farm at pro.startmining.io/farms and test your scenarios on the simulator at pro.startmining.io.
