Group mining-Групповой майнинг


Cryptocurrency mining in a pool is an excellent answer to the question of how to start mining on a home computer without buying or building a powerful farm (or at least a rig). Miners will unite in groups, and the reward for the found block is divided among all participants. Therefore, even the owner of not very productive equipment can count on a small share.

For mining in the pool, you can use a PC with a modern video card, the amount of video memory of which is at least 4-6 GB GDDR5, even better - 8 GB or more. If the equipment is assembled independently and specifically for cryptocurrency mining, you can buy a motherboard with support for 6, 8 or even 12 graphics cards - for example, ASUS Prime H270-PLUS.

To connect video cards, you will need risers, and for the device to work, you will have to buy an SSD drive of at least 120-160 GB and a modern, but not necessarily productive processor. All this is collected in a separate building.

The mining algorithm in the pool is as follows:

Open a cryptocurrency wallet on a crypto exchange such as Binance or Bittrex.
Choose the right pool. You should be guided by ping (at least 100 ms), total hashrate (the more, the better) and the minimum payout threshold.
Download the mining program, choosing it according to the type of coin and the brand of the video card. For Ethereum and an Nvidia card, the GMiner utility is suitable.
Put the equipment into operation and start mining.
Additional settings will help to increase the efficiency of the assembled rig or a computer with a powerful video card. To do this, you can use the MSI Afterburner utility or similar softw
