Really? How?

I changed my laptop and I thought about using the old one for a full node but I was looking at some information, and as I saw that it wasn't just two clicks, I left it for later and the old laptop is still waiting for me.

But I don't see the unbanked setting up a node. I doubt they can afford a laptop to begin with. If they had one, I doubt they would use it as a node, as there are much more productive things they can do. The node also has a cost in terms of electricity and we have to think that not all over the world there is broadband internet or flat plans, if they have to pay for GB used there's no way they are going to set up a node.

Maybe there is an easy and cheap way to set it up and that is what you are thinking of.
