PANews reported on March 25 that according to Bloomberg, due to the upcoming Bitcoin halving event, American mining companies are also dealing with their old models of mining machines while constantly buying new mining machines to expand computing power. About 6,000 old Bitcoin mining rigs will soon be idle and sent to a warehouse in Colorado Springs, where they will be refurbished and resold to overseas buyers looking to make a profit from mining in a low-cost environment. With electricity being the largest expense in Bitcoin mining activities, mining companies, including publicly traded companies Marathon Digital and Riot Platforms, need to reduce their cost of use to maintain positive profits. Theoretically, the hashrate of the old mining rigs may still be profitable after the halving, but it is unlikely to be realized in the face of high electricity bills in the United States.
Ethan Vera, COO of crypto mining service provider Luxor, estimates that about 600,000 S19 series miners (the majority of the machines currently in use) are being transferred from the United States to Africa and South America. Some buyers will wait until the halving takes place to buy a used miner, believing that the price will drop even more at that point. According to the data, in March 2022, the price of a used S19 model mining machine was about $7,030. A year later, as the price of Bitcoin fell, the price of the used S19 dropped sharply to about $900. With the replacement of mining machines, the second-hand S19 has fallen to about $427 this month, and it is expected to sell for about $356 after the halving in May.
In addition, there are also a portion of U.S. miners who choose not to sell their hardware, but only move their equipment to regions and third-party data centers where the cost of electricity is lower.
