Simply just another term for “Pool Mining”, Group Mining refers to a team of miners who combine their computing power and split the mined digital coin across all the mining participants. In this mining scheme, a large number of blocks, disproportional in nature, are mined by pools instead of individual miners.
Group Mining and companies are reported to constitute the large percentages of Bitcoin’s computing power. This method of gathering digital coins is an offshoot from individual Bitcoin mining that is usually done through ASICs. Using desktop computers, GPUs or older versions of ASICs, are far from being recommendable given that the cost of energy consumption exceeds that of actual revenue generated from mining.
