What is Bitcoin mining?

Bitcoin mining is the process of using specialized computer hardware (ASICs) to validate transactions and secure the Bitcoin network. Miners compete to solve cryptographic puzzles using the SHA-256 algorithm, and successful miners receive block rewards in Bitcoin. As of 2024, the block reward is 3.125 BTC following the April 2024 halving.

What is an ASIC miner?

ASIC (Application-Specific Integrated Circuit) miners are specialized hardware designed specifically for Bitcoin mining. They are significantly more efficient than general-purpose computers for performing the SHA-256 hash calculations required for mining. Major manufacturers include Bitmain (Antminer) and MicroBT (Whatsminer).

How does Bitcoin mining difficulty work?

Bitcoin's mining difficulty automatically adjusts every 2016 blocks (approximately every 2 weeks) to maintain an average block time of 10 minutes. If more miners join the network and blocks are found faster, difficulty increases. If miners leave and blocks slow down, difficulty decreases.

What is a mining pool?

A mining pool is a group of miners who combine their computing power (hash rate) to increase the probability of finding blocks. When the pool successfully mines a block, the rewards are distributed among participants based on their contributed hash power. Common payment methods include PPS (Pay Per Share), PPLNS (Pay Per Last N Shares), and FPPS (Full Pay Per Share).

What is hash rate in Bitcoin mining?

Hash rate measures the computational power used in mining, typically expressed in terahashes per second (TH/s) or exahashes per second (EH/s) for the entire network. Higher hash rates increase the probability of finding valid blocks. Modern ASIC miners can achieve hash rates of 100+ TH/s.

What is the current Bitcoin block reward?

As of 2024, the Bitcoin block reward is 3.125 BTC per block, following the halving event in April 2024. Bitcoin undergoes a halving approximately every 4 years (every 210,000 blocks), reducing the block reward by 50%. The next halving is expected around 2028, when the reward will decrease to 1.5625 BTC.

How is mining profitability calculated?

Mining profitability depends on several factors: hash rate (TH/s), power consumption (watts), electricity cost ($/kWh), Bitcoin price, and network difficulty. The key metric is efficiency, measured in Joules per Terahash (J/TH). Lower J/TH means more efficient mining. Profitability = (Hash Rate × Hash Price) - (Power Consumption × Electricity Cost).

Bitcoin Mining Laws in El Salvador

Overall status: Legal. Bitcoin remains legal property after the Jan 2025 amendments under the IMF Extended Fund Facility removed mandatory merchant acceptance and the legal-tender characterisation. Mining is fully legal and government-supported (state-run geothermal mining).
