By downloading and verifying the blockchain, bitcoin nodes are able to reach consensus about the ordering of events in bitcoin. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new units available to anybody who wishes to take part.
An important difference is that the supply does not depend on the amount of mining. In general changing total miner hashpower does not change how many bitcoins are created over the long term. Difficulty The Computationally-Difficult Problem Mining a block is difficult because the SHA hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros.
The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information. The Difficulty Metric The difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. The rate is recalculated every 2, blocks to a value such that the previous 2, blocks would have been generated in exactly one fortnight two weeks had everyone been mining at this difficulty.
This is expected yield, on average, one block every ten minutes. As more miners join, the rate of block creation increases. As the rate of block generation increases, the difficulty rises to compensate, which has a balancing of effect due to reducing the rate of block-creation.
Defaults The starting difficulty is taken to be the current difficulty. The USD exchange rate is taken to be the daily volume-weighted average exchange rate reported by Bitstamp. These values are updated periodically throughout the day. The remaining default values are fixed.
Data Exchange rate are obtained from Bitstamp. Statistics about the bitcoin network difficulty, block count, etc. To determine appropriate values for the remaining parameters, additional data are available from external sources on US electricity rates , EU electricity rates , historical difficulty levels , and mining hardware hash rates and power consumption.
More Details All calculations assume that mining begins immediately. The current block number is taken to be length of the current longest blockchain as given updated every fifteen minutes. Calculations begin at the given difficulty. The number of days until the first difficulty adjustment is taken to be the ETA estimate provided by blockexplorer.
Subsequent increases are assumed to occur regularly according to the specified interval.

We also use the current Bitcoin price in our calculations, but you can change the Bitcoin price to anything you'd like to get better data. However, there are numerous factors that affect mining profitability , and often times they are out of your control. Some seem to believe they will be able to quit their nine-to-five job after investing in a few Bitcoin miners — unfortunately, that is not necessarily the case. How do you know if mining is right for you?
It is important to understand the constantly changing dynamics that play into mining profitability, especially before you invest your hard-earned money. Nevertheless, a proper passive income can be generated if you play your cards right. Let's explore the factors that you need to consider before you buy mining hardware: Initial Investment The initial investment in efficient mining hardware is probably one of the things keeping you from pulling the trigger, and for good reason.
Mining hardware is expensive! In case you were not aware, the vast majority of mining operations are in China, primarily because of cheap electricity more on that later. Since ASICs are expensive, many average consumers do not have the capital to invest. The result? Large mining corporations operate mining farms with thousands of ASICs. Instead of mining being spread out across the world, the validation process is controlled by fewer people than first anticipated upon Bitcoin's inception.
Some hardware might not pay itself off at all. The additional factors below are largely responsible for determining your ROI period. You can use the calculator above to determine your projected earnings based on the ASIC you're using, and your electricity cost. Bitcoin's block time is roughly 10 minutes. Every 10 minutes or so, a block is verified and a block reward is issued to the miner. When Bitcoin was first created, miners received 50 BTC for verifying a block. Every , blocks — roughly 4 years — the amount of BTC in the block reward halves.
As the Bitcoin block reward continues to halve, the value of Bitcoin is predicted to increase. So far, that trend has remained true. First, the amount of newly minted BTC often referred to as coinbase, not to be confused with the Coinbase exchange halved to 25 BTC, and the current coinbase reward is Eventually, there will be a circulating supply of 21 million BTC and coinbase rewards will cease to exist. If BTC is no longer minted, mining won't be profitable anymore, right?
Bitcoin transaction fees are issued to miners as an incentive to continue validating the network. By the time 21 million BTC has been minted, transaction volume on the network will have increased significantly and miners' profitability will remain roughly the same.
Of course, block rewards have a direct impact on your mining profitability, as does the value of BTC — since the value of BTC is volatile, block rewards will vary. Additionally, successfully confirming a block is the only way you will generate any revenue whatsoever by mining.
Hashrate On a simple level, hashrate is the way we measure how much computing power everyone around the world is contributing toward mining Bitcoin. Miners use their computer processing power to secure the network, record all of the Bitcoin transactions and get rewarded in bitcoin for their efforts.
The higher the hashrate of one individual Bitcoin mining machine, the more bitcoin that machine will mine. The higher the hashrate of the entire Bitcoin network, the more machines there are in total and the more difficult it is to mine Bitcoin. Notes: Some values e. However, you can adjust any value manually to simulate possible scenarios. Couple of Points to Remember: This calculator estimates the revenue you could make.
Revenue is based on current difficulty to mine Bitcoins, which can vary and may go up over time. How to Calculate Bitcoin Mining Profitability. The higher the number of miners you have, the more decentralized and secure the network is. To compensate and encourage miners to provide mining services, an incentive system was created. This system provides a fixed amount of bitcoins to a miner when they mine a block, also known as a block reward. When looking at mining profitability, there are numerous factors to be considered: 1.
Hardware Costs This upfront cost is usually the largest expense for any new mining operation. The quality and capability of mining equipment varies greatly, as does the cost. While there are many options for mining hardware, there are three main manufacturers on the market today. If you are new to mining, it can be challenging to determine what hardware, or rig, to choose.
The higher the hash rate, the more powerful the mining rig. Hardware is powered by electricity and also generates a high level of heat. For these reasons, your hardware costs should also include considerations for power supplies and cooling equipment. Hardware Efficiency Hash power is not the only measure of quality when looking at hardware. You also want to consider the efficiency of the bitcoin yield relative to the amount of electricity consumed.
Power Costs Electricity costs can quickly change the profitability of mining operations.
