The QC-1 crypto heater

Mine and heat yourself at the same time

I still argue that cryto currency is only beginning, and not phasing out. There will probably be a heaps of these kind of innovations in the years to come.

i don't think this is new per se. i remember reading about this a year ago or more. and it is a very strange thing in my opinion because although mining equipment make a lot of heat but you need to cool them not use them in high temperature and let them heat your apartment. if you don't cool them down they will continue gaining temperature and eventually overheat and break down.

although keeping the GPU cool is essential, that does not mean letting that heat escape someones house immediately aftr taking it away from the GPU. that heat can be utilised by heating water to keep an ambient water heater/radiator

the downsides are:

1. 30 months+ ROI
2. the more people mining = more fingers in the reward pie = less reward = longer than 30 months ROI
3. the heat of 2 GPU's is not enough to warm a room in winter, but to keep a room at an ambient temperature
4. during the bitcoin GPU mining era people were needing to upgrade their rigs every 3-6 months(not 30+)

seems people didnt learn the inefficiency lessons of 2012-2013 (btc GPU mining era)
seems people didnt learn the self annihilating competition game of making mining a easy to do at home craze of 2012-2013
