Buying used Miners

Waste of time if you dont have a good place away from any house.

If your place is tiny dont mix gpu with asics.

Mixing GPUs with ASIC doesn’t affect anything. Many years ago most retail miners had tons of ASICs at their home and they also had GPUs.

ASICs also take up much less room than a GPU rig. The biggest difference is that the ASICs are crazy loud. So you can mine at home but the rigs need to be in a separate room such as a basement. You can’t sleep in that room.

"ASICs are crazy loud"

GPU and ASIC mixed give a lot of problems if the intake air temperature is not low.

Not all asics are loud

"if not loud then it's not worth"
