I've been stacking stats quietly for a few years. I don't have much, but its self custodial and cold. I'll keep going until I can go completely off grid. I've been working on a small but powerful NUC that can run my off grid life. BTC & LDN node, automation, backups, data, sensors, media, nextcloud etc. Power spikes to 65W, and idles at about 12W. Small steps.
