You can use lightning payouts with Ocean too. You have to set up a bolt-12 invoice. I have my sats transferred to my node every found block.
Yep. I used it once. Works well.
The S9 doesn’t do much for sats any more. But the room my office is in doesn’t have heat at all so I have to run something. This at least pulls less watts than a ceramic heater and I get a little trickle of sats.
If it's less watts than another heater then it makes sense to do it.
