Co-Founder

Les Femmes orange, terahash.space

I came across bitcoin in 2017, understood bitcoin in 2020 and have worked for bitcoin since 2022.
I work full-time with terahash.space, carrying out research on bitcoin mining in combination with renewable energies to provide energy solutions for individuals and businesses. I co-founded Les Femmes orange in November 2022, with a team of like-minded women, to encourage more women to study bitcoin.
