Cryptocurrency Mining: How It Works, Who Does It, and Why It's Changing
When you hear cryptocurrency mining, the process of validating blockchain transactions and adding them to the public ledger by solving complex math problems. Also known as proof of work, it's the original engine behind Bitcoin and many other coins. But today, it’s not about running a laptop in your garage and earning free coins. It’s a high-stakes, energy-heavy operation dominated by industrial-scale farms with thousands of machines.
At its core, cryptocurrency mining relies on proof of work—a system where computers compete to solve cryptographic puzzles. The first to solve it gets rewarded with new coins. But as networks grew, the puzzles got harder. What once took a home PC now needs specialized hardware called ASICs, which cost thousands and use as much power as a small refrigerator. That’s why mining hardware is no longer something you buy off Amazon—it’s a business decision. Most individual miners lost money after 2021, when electricity prices rose and Bitcoin’s reward halved. Now, only those with cheap power, bulk discounts, and technical know-how survive.
And here’s the twist: most major blockchains are moving away from mining entirely. Ethereum switched to proof of stake in 2022. Cardano, Solana, and others never used it. That means the future of blockchain validation isn’t about grinding processors—it’s about locking up coins to help secure the network. Mining still exists for Bitcoin and a few others, but its role is shrinking. If you’re thinking about jumping in, ask yourself: are you chasing a fading model, or are you prepared to run a mini-factory?
What you’ll find below isn’t a guide to starting mining. It’s a collection of real stories about what happened when people tried—whether it was chasing free tokens from a mining-linked airdrop, getting stuck with outdated gear, or discovering that a "profitable" mining pool was a scam. Some posts expose fake mining projects. Others show how blockchain validation works without mining at all. And a few reveal why even the most technical users walked away. This isn’t hype. It’s what actually happened.

What Are Block Rewards in Cryptocurrency? How Miners and Validators Get Paid
Block rewards are the payments miners and validators earn for securing blockchain networks. They include newly minted coins and transaction fees, and they're key to how cryptocurrencies like Bitcoin and Ethereum stay secure and decentralized.
