    Der bewusst provokante Titel dieses Blogposts soll auf eine Tatsache aufmerksam machen: Bitcoin und andere Kryptowährungen haben ein ökologisches Problem.

    So I bought a used phone, because I sold my HTC Desire with CyangenMod 7 installed and a2SD running. A great phone, and a fantastic ROM. Especially the keyboard, predictive text.  But its battery was only lasting for 8 hrs and I got tired of Android 2.3. I swore to myself, that I would not…
