Hi, thanks for the note, nice to meet you. I followed you as well.
I started with BOINC and GRC in March and at that time I had two computers. One was an older gaming laptop (windows 10) and the other was a Pi2 that was just collecting dust. I have the wallet running 24/7 on my laptop, but due to poor thermals I can only crunch BOINC with 1 or 2 of its cores (out of 4) when the wallet is running. Maybe it would make sense to move the wallet over to the old Pi 2, or maybe one of the Pi 3s. Please do send the compiling guide, I'll give it a try.
Regarding the exchanges, I've only ever used c-cex and polo. I know customminer always suggests other options that aren't centralized, so maybe there are better places to do business that I just haven't tried out yet. Yeah, Lykke's model seems really cool, a lot better than polo.
Actually you have a few options, if you make one of your Pis run Ubuntu there is a Gridcoin PPA that should be very easy https://launchpad.net/~gridcoin/+archive/ubuntu/gridcoin-stable . I didnt use it myself.
Another option is whats going on over at https://github.com/Steffov/GRC-Scripts . I didnt use it myself.
The compiling guide I wrote is pretty long, see about the others first and if they are no good for you perhaps I'll publish it on my own GitHub
will do, thanks
