What Is Mining?
Mining is the work that powers proof of work: specialized machines guessing at cryptographic targets to win the right to add Bitcoin's next block, earning newly issued coins plus fees. It is simultaneously the network's security budget, its coin issuance, and a brutally competitive global industry.
How It Actually Works
- ASICs, purpose-built machines useless for anything else, hash around the clock. Finding a valid block pays the block subsidy (cut in half every four years by the halving) plus transaction fees.
- Individual luck is too lumpy, so miners join pools that share rewards proportionally to contributed hashpower, which smooths income and concentrates coordination.
- Difficulty adjusts every two weeks so blocks average ten minutes no matter how much hardware competes. More competition never means more coins, only a thinner slice each.
The Economics, Honestly
- Margins live and die on power prices, hardware efficiency, and the coin's price. Halvings periodically bankrupt the least efficient.
- Bills are in dollars, revenue in BTC, so miners sell continuously: billions per year of structural flow, background pressure sized honestly on my learn page.
- Public mining companies increasingly moonlight their data centers for AI compute, a diversification worth knowing when reading their headlines.
Risks and Common Mistakes
- Home mining Bitcoin in 2026 is a hobby with an electricity bill, not an income. Do the power math first.
- "Cloud mining" contracts sold to retail are overwhelmingly poor deals or outright scams. Buying the coin is almost always the better version of the same bet.
