I think I figured it out.
I tried the win64 last night and it didn't work out of the box. It didn't sync with the network, possibly due to my firewall, not sure. So I tried connecting directly to my buddy's node using the Debug Console with the command:
addnode "34.127.37.138" onetry
There's gotta be a way to add nodes in the config file but I'm not there yet.
Manually adding nodes feels like a real peer-to-peer cryptocurrency :-)
Send me some Potreros if you found this useful.

That does not mean it is an official one. Like you said, it is your buddy's node. which means he started to mine on his own, which makes it a fork of the blockchain.
If we mine with this node, we mine on another chain than the official one. This is not the way.
