## Profitability of ASIC mining

In calculating your potential profit, keep in mind the following factors:

The cost of your ASICs

Electricity costs to run the hardware

Cooling costs—ASICs generate a decent amount of heat

Your percentage of the total network hashing power

To calculate the expected rewards from mining, we can do the following. First, calculate what percentage of total hashing power you command. To look up the network mining speed, execute the `getmininginfo`

command in the console of the Bitcoin Core wallet. We will do our calculations with an ASIC that can hash at 1 TH/s.

If the Bitcoin network hashes at 400000 TH/s, then our proportion of the hashing power is as follows:

**1 / 400 000 = 0.0000025 of the total mining power.**

On average, a Bitcoin block is found every 10 minutes, so six per hour and 144 for a 24-hour period. The current reward per block is 25 BTC, therefore in a day we have *144*25 = 3600* BTC mined.

### Note

If we command a certain percentage of the mining power, then on average...
