BitcoinMiningStock.io
Business Description
BitcoinMiningStock.io is an independent data platform and financial-services research hub co-founded by Hayden Otto and Cindy Feng. Feng previously served as global marketing manager at one of the largest publicly traded Bitcoin miners. The platform took shape after Feng observed at Mining Disrupt 2023 that publicly traded digital asset companies were not communicating the operational metrics investors needed, and that mainstream stock screeners were not built to surface them.
The platform organizes its coverage across three verticals. Its Bitcoin mining stocks tracker aggregates real-time and historical data on hash rate, BTC production, market capitalization, and enterprise value for publicly traded miners, sourcing every data point to SEC filings or investor-relations disclosures, with source labels visible on each table. A second vertical tracks AI and high-performance computing data center companies, monitoring power capacity, hyperscaler deals, and satellite-identified data center locations. The third covers crypto treasury companies holding Bitcoin, Ethereum, or Solana on their balance sheets, with holdings history and comparative data.
As of 2025, BitcoinMiningStock.io tracks 268+ publicly traded companies, maintains 100,000+ data points updated daily, and serves 6,000+ monthly users. The platform's proprietary Bitcoin Mining Index, launched in early 2024, benchmarks the public mining sector rather than relying on generic equity indices. Additional financial-services tools include an enterprise-value-per-exahash metric, a stock heatmap, an earnings calendar, earnings-call transcripts with AI-generated summaries, insider trading disclosures, and a custom index builder on paid tiers.
Subscription tiers range from a free Observer plan through a Professional tier at $29 per month (adding multi-year historical data with source links, AI earnings summaries, and advanced screening) to a Basic API plan at $149 per month providing programmatic access at five calls per second. Enterprise API licensing with custom rate limits and white-labeling is available on request.
The platform combines financial services data with media and advisory content. In late 2024, Bitcoin.com began syndicating BitcoinMiningStock.io's analysis reports, expanding reach across its media network. Compass Mining's podcast featured co-founder Cindy Feng in April 2025 to discuss company-investor communication gaps in digital asset equities, indicative of the platform's advisory and educational positioning. Its 2025 Bitcoin Mining Annual Review, produced with analyst Nico Smid of Digital Mining Solutions and published in January 2026, covered network hash-rate trends, the HPC sector pivot, and ASIC hardware cycles, functioning as both an educational resource and an advisory reference point for institutional and retail participants tracking the mining industry.
