When you hear about Bitcoin mining reward, the amount of new Bitcoin paid to miners for validating transactions and adding blocks to the blockchain. It's the engine that keeps Bitcoin running without banks or central control. Every ten minutes, a new block is added to the Bitcoin blockchain—and whoever solves the math puzzle first gets paid. That payment is the block reward, the fixed amount of Bitcoin awarded per mined block. Right now, that’s 3.125 BTC. But it hasn’t always been this way, and it won’t stay this way forever.
The Bitcoin halving, a scheduled event that cuts the mining reward in half approximately every four years. happened in 2012, 2016, 2020, and 2024. Each time, the reward dropped: from 50 BTC to 25, then 12.5, then 6.25, now 3.125. This isn’t just a technical detail—it’s a core feature designed to limit Bitcoin’s total supply to 21 million. That scarcity is why people call it digital gold. But here’s the catch: as the reward shrinks, miners rely more on transaction fees to stay profitable. If fees don’t rise enough, some miners shut down. That could slow down the network or make it less secure. And that’s why tools like the ASIC miner profitability calculator, a tool miners use to estimate earnings based on hash rate, electricity cost, and block reward. are so critical. They help miners decide whether to keep running their machines or cut their losses.
The posts below dig into what’s really happening on the ground. You’ll find real-world breakdowns of how mining rewards affect miner behavior, why some ASIC miners are going offline after the 2024 halving, and how electricity costs in places like Texas or Kazakhstan make or break profitability. You’ll also see how other crypto projects tried to copy Bitcoin’s model—and failed. There’s no fluff here. Just clear, practical insights on what the mining reward means for you, whether you’re holding Bitcoin, running a miner, or just trying to understand why this system still works after 15 years.
Bitcoin halving is a programmed event that cuts the mining reward in half every four years, reducing new Bitcoin supply and reinforcing its scarcity. Learn how it works, why it matters, and what to expect next.
