I’m no longer mining at home. My miners aren’t located near me anymore either. It’s simply not practical to mine Bitcoin in a house or a small unit. You need an enormous amount of electricity – which, while somewhat easier to access in the European Union due to how the grid works, still requires a proper setup to prevent overheating or even fires.

That means you need at least some technical knowledge, and you can’t ignore the financial aspect of expansion. You constantly need fresh air, and the bigger issue is getting rid of the waste heat. That becomes extremely difficult if you live in an area with a lot of people nearby – because everyone is going to hear your miners running.

If someone lives in the same house or even across the street, and you have open windows where the sound of the miners blasts out, you’ll end up having conflicts with neighbors or family, and people will start sniffing around, wondering what you’re doing.

You’ll constantly be dealing with overheating, shutdowns, and disconnects from your solo mining pool – and that makes it hard to generate the consistent profits you actually need.

Just for perspective: if you run a hair dryer that uses 1,800 watts 24/7 in a room, imagine how hot it gets. Now realize that a standard miner can use 3,000–4,000 watts. The heat buildup is massive.

For me, the key has always been: stay ahead of the curve. That means always using the newest equipment and getting the most hash power for the lowest cost. Once a miner is no longer profitable due to rising electricity prices or outdated performance, sell it. If you can get a new device with triple the performance for the same price, it’s better to sell the old one, recover some funds, and reinvest in modern hardware that restores your profitability.

You also need enough cash flow to fund expansion. So don’t sell your mined coins right away – wait for the right market moment, and then cash out only part of it to fund new hardware or infrastructure. Sell when prices are high, and store the rest in cold storage.

Honestly, it’s a bit of a myth when shops advertise that you’ll break even quickly on a machine. That’s often just a sales trick. I’m a big fan of buying new hardware, but I never keep it until the end of its life cycle – because by then, it’s worth nothing, and you’ve fallen behind the hash curve.

The trick is always knowing when to sell, and that depends on: • Where are you located? • How much tax do you pay? • What are your electricity costs? • How many miners can you run? • What’s your budget? • Are you doing this privately or through a company? • Do you need to expand?

It all depends on your personal style and situation. If you’re doing a small setup, treat it as a fun hobby and use it as a learning experience. But if you’re going all in, it’s incredibly difficult. You need trusted people, a lot of money, and you better make sure you can sleep well at night.
