swissminers.net is a non-profit organization that represents crypto mining companies and interested individuals. In 2011, we experimented with mining Bitcoin using field-programmable gate arrays (FPGAs), followed months later by our first GPU-based mining rig. By late 2013, we upgraded to the Bitmain Antminer S1, the very first ASIC Bitcoin miner on the market. To minimize noise and energy costs, we immersed the devices in food-grade oil. We mainly operate our mining farms in countries with low energy costs and produce our own electricity using wind, hydropower, and solar energy.
