Right now, nothing. It's supposed to be my main lightning node. I used to use it for a bit of routing (never profitable), and for broadcasting my own transactions from command line (a good educational experience). But ever since I wiped it and rebuilt it and it took a month to IBD, I lost interest a bit. Primarily just using Alby Desktop for now. Overall though, my goal of having this node would be to validate blocks myself, broadcast my own transactions, help the network, and run a more stable lightning node than my current Alby Desktop (which isn't always on.)
