Radically transparent

Founders

Sascha discovered Bitcoin in Berlin in 2012. Over the next decade, he tried every mining model — and lost more than CHF 250,000 to hidden fees and broken promises.

In 2022, Valentine partnered with Sascha to build what the industry was missing. Green Mining was founded on three principles: co-ownership, transparency, and aligned incentives. They hold the same shares as every investor.

Our Founders' Experience

We know because we lived it. Before building Green Mining, our founders lost more than CHF 250,000 in failed mining ventures. That pain shaped every decision since.

The team

Building the most transparent Bitcoin mining company in the world.
