# Simple Mining

> Simple Mining is a Bitcoin mining hosting, miner sales, and ASIC repair company based in Cedar Falls, Iowa, serving retail and institutional operators across the globe.

Simple Mining operates 9+ EH/s of hashrate across roughly 150 MW of capacity at ten operating sites in Iowa, with an eleventh coming online, on a grid mix that is approximately 60% wind and solar. The company sells current-generation Bitmain ASIC miners, hosts them in U.S. facilities at all-in rates of $0.065–$0.08/kWh, and operates one of the largest in-house Bitmain-certified ASIC repair facilities in North America. Customers retain hardware ownership. Simple Mining bills only for actual hashing uptime under precision billing, includes Year 1 Repair Coverage with free repair labor and a $500 annual parts allowance per miner on units purchased from Simple Mining, and offers a free 7-day trial on an Antminer S21-class unit before any capital commitment. All sites run 24/7 on-site security and average 95%+ uptime. Simple Mining is also developing a portfolio of 200-plus megawatts of Tier 3 AI data center infrastructure across the Midwest for AI companies, hyperscalers, and capital partners.

Founded by Adam Haynes. Headquartered in Cedar Falls, Iowa.
