Solo Mining: What It Is, Why It’s Hard, and What You Can Actually Do in 2025

When you hear solo mining, the act of mining cryptocurrency using your own hardware without joining a mining pool. Also known as individual mining, it’s the original way to earn crypto—directly from the blockchain, no middlemen, no sharing rewards. Sounds simple, right? But in 2025, solo mining Bitcoin with a home rig is like trying to win the lottery with one ticket every week. The network’s hash rate is over 1,000 exahashes per second. That’s more computing power than the top 500 supercomputers combined. If you’re using a consumer GPU, your chance of finding a block is less than 0.0001% per year.

That’s why most miners join pools—where they combine computing power and split rewards. But solo mining still exists, and it’s not dead. It’s just shifted. ASIC miners, specialized hardware built only for mining specific coins like Bitcoin are the only machines that make sense for Bitcoin solo mining today. Even then, you need access to cheap electricity, cooling, and a stable internet connection. Most people who try it lose money on electricity before they ever see a single BTC.

But if you’re looking for real solo mining opportunities in 2025, look at GPU mining, using graphics cards to mine coins that still resist ASIC dominance. Coins like Monero (XMR) and Ravencoin (RVN) are designed to be mined with GPUs. They’re resistant to ASICs, which keeps the playing field open. If you have an old gaming rig sitting unused, you might still turn it into a small income stream—especially if you live where electricity costs under $0.05 per kWh.

Solo mining isn’t about getting rich. It’s about independence. No pool fees. No payout delays. No trust issues. You either find the block and get the full reward, or you get nothing. That’s the gamble. And in 2025, that gamble only makes sense for a few people: those with access to near-zero-cost power, deep technical knowledge, and the patience to wait months—or years—for a single block reward.

That’s why the posts here focus on the real-world side of mining. You’ll find reviews of exchanges that claim to offer mining services (spoiler: most are scams). You’ll see how Sweden’s energy laws are pushing miners out. You’ll learn why Bitcoin mining is now a factory business, not a hobby. And you’ll find guides on altcoins that still let regular people mine profitably with old hardware. This isn’t a hype page. It’s a reality check.

If you’re thinking about solo mining, ask yourself this: Are you mining for the thrill, or the returns? If it’s the returns, you’re better off staking, trading, or even just buying and holding. But if you want to understand how the blockchain works from the ground up—how blocks are solved, how rewards are distributed, how power and hardware shape the entire system—then solo mining, even if you never earn a coin, still teaches you more than any YouTube video ever could.
