Although it takes 10 minutes to discover each block, and each block yields a 6.25 BTC reward for the miner that successfully discovered it, it’s important to understand that the entire Bitcoin mining network is essentially competing in this block discovery process.
Based on the inputs for the mining hardware, 0.00047785 Bitcoin may be mined each day, with a hash rate of 140.00 TH/s, a block reward of 6.25 BTC, and a difficulty of 36,835,682,546,788.00
Bitcoin Mining is done with powerful hardware to tackle a very challenging computational arithmetic problem. Mining cryptocurrency is time-consuming, expensive, and only sporadically profitable.
