Crypto mining
Also called: mining · bitcoin mining
Definition
Crypto mining is the process of using specialised computers to secure a proof-of-work blockchain by adding new blocks, in exchange for newly issued coins and transaction fees.

How Crypto mining works
Miners collect pending transactions, build a candidate block and then race to find a hash that meets the network's difficulty target. The winner broadcasts the block, other nodes verify it, and the miner receives the block reward plus fees. On Bitcoin that reward is 3.125 BTC per block since the April 2024 halving.
Mining today is an industrial business. Bitcoin is mined with ASICs, chips built for a single hashing algorithm. Profitability depends on the coin price, the machine's efficiency, the electricity price and the network's total hash rate. When many new machines join, each miner's share of rewards shrinks.
Because a single miner might go months without finding a block, most join mining pools that combine hash power and share rewards in proportion to the work submitted. Be careful with cloud mining offers that promise fixed daily returns; many are scams, and legitimate ones still carry the same price and difficulty risks.
Example
Suppose a miner runs one ASIC that earns about 0.00012 BTC per day at current difficulty. At an illustrative BTC price of 70,000 USDT, that is 8.40 USDT per day. The machine uses 3.2 kWh per hour, or 76.8 kWh a day. At 0.08 USDT per kWh, electricity costs about 6.14 USDT, leaving roughly 2.26 USDT of daily gross profit before hardware costs, pool fees and repairs. If electricity cost 0.12 USDT per kWh, the miner would make a loss of about 0.82 USDT a day.
Common mistakes
- Calculating profit with today's difficulty and price as if they will never change.
- Paying for cloud mining contracts that promise guaranteed daily income.
- Forgetting cooling, noise, hardware wear and local electricity rules when mining at home.

FAQ
Is crypto mining still profitable?
It depends on electricity costs, hardware efficiency, coin price and network difficulty. Large operations with cheap power have a big advantage over home miners.
Can you mine Ethereum?
No. Ethereum stopped mining when it moved to proof of stake in September 2022. Validators now secure it by staking ETH.
What is a mining pool?
A mining pool combines the hash power of many miners and splits rewards according to each member's contributed work, giving smaller miners steadier payouts.
