Cryptocurrency mining solo-Добыча криптовалюты соло

But there is also a very serious minus - choosing what you can mine on, you will have to buy an ASIC. That is, an expensive, usually not cheaper than $ 2000-3000, but a powerful device specially created to receive digital assets. The process of starting cryptocurrency mining in the "solo" mode can be represented as the following algorithm: Choose a cryptocurrency, download a cryptocurrency wallet suitable for it from the official website of the coin. Configure it by creating a configuration file and entering the login, password, IP and port in it. Download a suitable application for mining e - for example, BFGMiner. Make changes to the bat-file of the miner program - the text depends on the selected cryptocurrency and the data that was previously entered into the wallet configuration file. Save the bat file and run the wallet, after which the mining process should begin. The more powerful the equipment, the faster the cryptocurrency will be mined. Therefore, solo mining on a regular PC, even with a top-end video card (and even two), will not work. The payback will be low, and the list of suitable coins will be limited. And a novice miner should choose other options - mining in a pool or cloud services.
