The first question that will have to be decided is whether it is worth starting to mine cryptocurrency at all. Here, a lot depends on investments, the method of mining, and also on the right choice of coin. The most popular, though not necessarily the most profitable options right now are Bitcoin, Monero, Zcash, Ethereum, and Litecoin. You can check this on the WhatToMine service, where you should select the mining method (graphic cards or special devices, ASICs) and check the list. Starting to mine cryptocurrency, you can use another method - analyzing the statistics of mining pools. The 2miners.com service is suitable for this, where the algorithm for checking the payback of a certain cryptocurrency is as follows: Log in to the service. Find the "Miners Online" tab Scroll down the list and find a miner with the same power as the user's equipment. Suppose that such a device is the Asik PandaMiner B3 Plus, popular in 2021. For Ethereum, its performance is 220 Mh/s. Go to the miner's page by clicking on his nickname on the service. Check profit for the day, week and month. In this example, the user can expect $459.85 per month. This is enough to quickly pay for the PandaMiner B3 Plus, which costs about $2500 on AliExpress. When calculating the payback, it is worth considering also the cost of paying for electricity. So, for the PandaMiner B3 Plus model, it does not exceed $0.07/kW x 720 h x 1.25 kW = $63. The expected payback period is $2,500 / ($459.85 - $63) = 6.3 months. If this suits the user, you can stop at Ethereum - or check a few more coins on the same service, choosing the most profitable option. True, both of these methods are not suitable for cloud mining. When mining in the “cloud”, it is worth looking, first of all, for a good service, which will already allow you to avoid accidentally choosing a disadvantageous coin.
