Yeaaaa as an individual who mines for a living - this is just crap journalism. If they can show me the profits - I’ll rethink this but I’m willing to bet that it’s just not possible in the given time frame with residential power limitations…. As you have all said, 15A breakers (even at 208-240V) aren’t going to power enough hardware to generate that amount of BTC. kHeavyHash and Blake3 altcoin miners are the most profitable regarding electricity OUT/coins IN (in USD values) and even so - the Blake3 machine that could potentially do this isn’t shipping yet and costs a whopping 32K USD (so in reality - let’s just entertain that for a moment…. That would mean they had to mine nearly $500K USD to ROI and claim 100K of profit).
I do not doubt that there are people out there attempting this sort of thing - utilizing airBNB/motels for free electricity but like some of you have mentioned - the labor involved coupled with the risk due to variance in solo mining (as a sort of turn-key portable mining op would require for actual profitability) would make anyone with half a brain see that this is NOT feasible lol.
Not sure why someone went ahead to publish this - either those who did it were trying to impress someone and grossly exaggerated everything, they themselves utilize airBNB to rent their own properties and someone did something like this - this they are trying to indirectly give miners a bad name, or the third option - attention-craving / boredom perhaps?
Anyway - if anyone sees this headline and thinks “what a fantastic idea!” - think again. Attempting this is a monumental waste of time.
