21 sats \ 3 replies \ @Brunswick 30 Oct 2022 \ on: Heat your home while mining BTC bitcoin
It won't pay for itself. 14TH/s 1400W $0.15/KWH costs $5/day to run and you get $1/day of bitcoin. You'd need to run it for 1100 days 24 hours a day just to pay for it and you can pick up a much quieter ceramic heater that you could run only occasionally for under $50. Its more likely to get jammed in a closet because of it failing to work or for its noise before you get that many hours out of it. Not to mention that 14TH will likely be uncompetitive before that 1100 days of use rolls by. I like the idea but the efficiency has to be allot higher to make it economical.
Yeah, I'd like to see someone compare this against more traditional (and cheaper) heaters comparing both TCO and energy efficiency before I drop over a grand on a space heater.

This 1,400W bitcoin mining device provides essentially the identical energy efficiency of a 1,400W $30 space heater.
So if you would run a 1,400W space heater 24/7 for five months each winter, and would use this ASIC instead, your TCO over five years is ... impossible to calculate because there's no way to know the future bitcoin exchange rate and the future bitcoin difficulty.
But for the first year is (assuming today's price and difficulty):
TCO after one year:
Heatbit: $1,149, plus $69 shipping, minus $150 (revenue earned this winter), plus $150 for electricity for the winter, or $1,218.
Cheap space heater: $30, plus $150 for electricity for the winter, or $180.
Cheap space heater: $30, plus $150 for electricity for the winter, or $180.
Let's say in the second year this ASIC earns you $50.
Heatbit: $1,149, plus $69 shipping, minus $200 (revenue earned the two winters), plus $300 for electricity for two winters, or $1,318.
Cheap space heater: $30, plus $300 for electricity for the two winters, or $330.
etc. for years three and on, where the difficulty increases and thus bitcoin revenue from this device decreases as a result.
And that assumes you truly run the device 24/7 for the five winter months. Space heaters are oftentimes used only to supplement heat in a living area (i.e., run much less often than 24/7).

??? для обогрева помещения окупаемость не важная вещь... смотри на плату по счётчику... и все плати из кормана... а он будет часть брать из блок чейн... а это выгоднее чем просто жечь огонь в пустую... биткоин решает уже 2 проблемы одним выстрелом... один выстрел два зайца
