The decline in the rate of encryption and the increase in the complexity of Ethereum mining caused miners to start phasing out graphics cards in large numbers. In stores, their prices have also dropped, especially abroad, where they are sold for close to the recommended price.
Hundreds of advertisements for video cards from GeForce GTX 1060 to GTX 1090 Ti have appeared on Russian online platforms where used goods are placed. They sold less than a few months ago, when mining seemed to be a lucrative business. For example, a GTX 1060 sells for around 15-20 thousand rubles, while a more modern GTX 3080 card costs 60-80 thousand rubles.
Many sellers stated in their announcement that their video cards were not used for mining, others were more candid and wrote that the cards were obtained from farms. The fact that it is mined on a video card doesn't say anything about its condition. If the farm is assembled by skilled hands, cooled well and serviced on time, the video cards used in it will last a long time. Conversely, gamers frequently overclock, and some of them try to reduce the fan's noise and slow it down, which negatively affects cooling. When buying a video card from hand, it makes sense to double check it (eg, under benchmarks) and check it out. You can visually notice damage to textolite, contact paths, capacitors, transistors and other components if you work for a long time.
Considering its cost and the speed and complexity of cryptocurrency mining, the estimated payback period for video cards is currently 1000 to 2000 months, depending on the model. For example, the GeForce GTX 3080 Ti, minus electricity bills, only costs its owner about a dollar a day.
