Transaction fees for spends included in the block are also paid. The block subsidy is only one part of the full block reward paid to miners who win each block. Compare fees across different pools by substituting them into the Pool Fee field and see the effect on long-term profitability. Pool Feeįees can vary significantly across different pools, but rarely do pool fees rarely change, or at least change significantly. Otherwise the current block subsidy can be used. For most revenue calculations, adjust the block subsidy if the model is extended beyond the date of the next halving. This number changes after each halving event, which takes place once every four calendar years, approximately. The number of new bitcoins created when each block is mined is the block subsidy. Consider also slightly adjusting power prices up and down to see its effects on future profit. Even without that agreement in place, for the purposes of estimating future revenue, a miner can generally use their current power price for future projects. Prices can also vary over time unless a miner secures a power purchase agreement with future power price predictability. The cost of power is one of the data points miners care about most, and electricity prices can vary significantly across different geographic regions. Through normal use, power consumption can increase slightly over time or it can change significantly by choice of the operator when using tools like Braiins OS+ firmware.įind a machine’s estimated power consumption in the product details and, for miners operating more than one machine, simply sum the total expected consumption for all operational machines and, if appropriate, account for increases from overclocking with custom firmware. Every bitcoin mining machine specifies its factory estimated power consumption in the product details, but the real number can fluctuate. Miners usually measure their power consumption in watts (W) per hour (W/h) or kilowatt hours (kWh). Power consumption is one of the most important data inputs for any mining operation’s profit calculations, and unlike other data, it’s relatively easy to predict although it’s not a fixed number. See historical hashrate data on the Mining Insights dashboard. Find the hashrate for whatever machines are (or will be) operational, and sum the total hashrate for all operational machines. Hashrate is generally measured in terahashes per second (TH/s). Every make and model of mining hardware has a factory estimated hashrate in the product details. Hashrate is a value derived from the estimated amount of hashes being generated to solve new blocks. See current difficulty level on the Mining Insights dashboard. Expected future changes in bitcoin’s mining difficulty are input in another field explained later in this post. Input the current network difficulty level to this field. Expected future changes in bitcoin’s price are input in another field explained later in this post. Input the current bitcoin price based on the number displayed by whatever exchange a miner prefers to use or a data aggregator like OnChainFX. This metric is also simple and easy to enter. Set the range on the Braiins calculator for whatever timeframe is appropriate, between 6 and 60 months. Focusing on longer time periods is a more common strategy instead of mining with very short-term profit expectations. The idea that Bitcoin incentives long-term planning is especially true in mining. One of the first and most simple inputs is the timeframe for measuring revenue and profitability.
