I think the gold standard is a fully bitcoin heated home. You'll need an immersion mining heat reservoir and modular heat exchangers for water, ventilation, hot tub, grow house, and whatever else you want heated. Get some old gen ASICs to keep capital costs low. Upgrade when they pay for themselves. Bonus points if you have solar and house battery.

The really wild stuff is applications you haven't conceived yet. I met a dude working out how to build an ASIC-enabled mesh wifi router. It passively mines sats and uses them to pay for mesh net access so we can deprecate ISPs. 🤯

The future is going to be wild!
