20W x 24 hours is about 0.5 kWh. I can export that for 4p. 100 sats is a similar value, so if I have to pay £150 for the unit then it's not really worth it. Money is not the only motivation for this anyway.
I think I'd rather run a Hive witness. I don't know what I would make, but it would be more interesting to me.
Very true. I don’t do it for the money either. I’m more interested in learning about the technology and How to get more Bitcoin Miners to move to Solar.
