You are right, this is simpler

Regarding the other distros and the automatic/minimum donation, I found 
that most major distributions*
patch out the minimum donation level(but keep the default of 1%) and few 
leave it unchanged.

+anti-functionality has been neutralised in Guix, but possibly not in all other
+distributions.

+Warning: This software, because of it's nature, has high energy consumption
+and will increase your carbon footprint. Also, the energy expenses might be
+higher that the cryptocurrency gained by mining.")
