How it works

Three steps.
Nothing else.

Seven Stars Data is a physical infrastructure business. We build generation assets, run computing hardware on that power, and convert the output to sterling. There is no platform, no token, no intermediary.

01

Generate

2MW solar + wind · Thoothukudi

We own and operate 2MW of solar and wind hybrid generation in Tamil Nadu. No utility contract. No power purchase agreement. Once commissioned, our electricity costs us nothing to produce beyond maintenance. This is the structural advantage.

02

Compute

400 × Antminer S19 XP+

400 high-performance mining machines run continuously on owned power. Each produces 368 TH/s of computing power, running the SHA-256 algorithm. The fleet operates 24 hours a day, managed from the UK and operated on the ground by our India team.

03

Convert

Bitcoin → GBP → UK bank

Bitcoin earned is converted to GBP through our institutional Coinbase Prime account and transferred to the UK parent company. Shareholders receive returns in sterling as dividends. No cryptocurrency exposure is passed to investors.

Strategic Risk Mitigation Analysis
By owning the physical asset generation capacity outright via Foreign Direct Investment pathways, the business eliminates variable utility rate inflation. When global grid tariffs spikes challenge other miners, our baseline marginal production inputs remain protected at near-zero.

Why owned generation is the whole advantage.

Our marginal electricity cost approaches zero because we own the generation. When Bitcoin's price falls and grid-dependent miners become unprofitable, they switch off. Difficulty falls. We keep running — and earn more.

Green Mining (greenmining.io) runs a similar model in Paraguay, paying $0.057/kWh for external hydro. Our structural cost is lower. Our production cost per Bitcoin is estimated at £20,000–30,000 versus their ~$54,000.

The comparable

This model exists. It works.
We are better positioned.

Green Mining (greenmining.io) proved the thesis: a holding company in a reliable jurisdiction, renewable-powered mining operations, returns to shareholders. Three facilities sold out. 300+ investors. 10% average ROI in 2025. The model is real. Here is how we compare.
