Home mining is mostly good for winter to offset heating cost.
In winter my cost goes to zero. Power needed to be spend anyway.
I had to put 2-3KW/h on copper wire to heat during winter.
Now I run same power with miners / GPU , same heating budget.
Downsize during summer.
I also share some older miners with friends to heat their place.
They do not invest, I take care of everything. 50-50 revenue split.
They offset heating cost, I juice out more revenue of my older miner.
This summer, I'm running a old C1 to heat a pool at a friend house.
It's a first test, need some improvements but it work very good.
No much revenue ( 50% of 1TH ) , but still I juice out some
There is many way to ROI hardware if your can re-use the heat.
