I am setting up a RPi3 Mining node for fun. I know that it will have less than 8 connections that are outgoing.
I know that if I was able to configure my network and router to allow incoming connections on port 8333 it would make my node work better.
My question is whether the incoming connections is required in order for the node to mine at all.
Will the outgoing connections that I make allow those peers to send my node transactions as those nodes get them, or is incoming connections the only way to get transactions that can then allow my node to mine blocks?
