The BitcoinMiningCost (BMC) Premium Beta is now open. Verified Nostr users can join instantly — simply sign in with your Nostr key. No registration, no email, and no personal data required.
One click with Nostr unlocks full Premium Beta access.
All core modules from the public dashboard are active: Efficiency Index, Multipool Comparison, Single Pool Analysis, Cost Maps, and ROI Calculator. The Beta gives you a complete analytical environment with extended datasets and deeper temporal coverage.
To maintain stability and focus during the Beta phase, several advanced tools are temporarily disabled:
These capabilities are in active development and will be introduced with the public Premium release, expected approximately two months after the Beta launch.
Access to the Premium Beta is powered by Nostr identity. Authenticate using your preferred client — Damus, Amethyst, Snort, or any compatible browser extension — and BMC will recognize your public key automatically. No profiles, forms, or verification emails are required.
This login method aligns with Bitcoin's open principles: privacy by design, ownership of identity, and censorship resistance.
The Premium Beta is designed to gather real-world usage data before enabling programmatic access. It helps us stress-test the platform's data ingestion, regional cost normalization, and modeling accuracy under live conditions.
We're also using this period to refine usability, interface performance, and feedback loops. You can share feedback directly through Nostr, in-app reports, or our GitHub repository — every insight helps improve transparency.
Signing in is simple:
No emails, no forms — just data transparency, powered by your key.
No registration. No email. Instant access.
