I prefer to have only enough hashrate to heat my living/work spaces.

Corporate megamines can't compete when you're mining for heat. The heatpunks are not so sensitive to price of electric. They will still add hashrate even as they're losing sats due to unprofitability because the "waste" heat is what they're mining for. This trend will absolutely devastate the bottom line of for-profit miners long-term.

Hashing proportional to one's stack is less achievable and is based on altruism if you're doing it unprofitably just for the sake of reaching an arbitrary hashrate target.

IDK if I would like to see Saylor and Blackrock control that much hashrate :)
