Built by Chris Johnson — Faith Mining LLC
IT Specialist at the FAA running a Bitcoin mining operation on the side. I built these tools because the existing ones are either paywalled, ad-choked, or just wrong. Everything here is free, open, and built on real numbers from a real operation. Questions or feedback? info@faithmining.net
