It's obvious that bitcoin miners are minting at very low % of profit.
The bigger ones try to hold as much as they can to seel in "pumps" like the one that we've seen before. The others just shut-off their rigs to don't pay more in electricity than what they really earn.
Could be interesting to have the testimonial of some miners and know if they hold or sell all their minted btc's
I often hear "only large industrial size mining farms can be profitable"
This sentiment gets repeated until it is largely accepted as "fact".
But a home miner does not need to lease a large factory space or airplane hangar, and in the winter the electricity is effectively free. So I think the small miners can still compete by virtue of having lower overhead costs.
As an example, my cost right now is approximately $100 per bitcoin mined, and I don't sell any.
Other miners please feel free to chime in...
$100 per coin including your hardware costs?
Yeah, hardware costs were recovered long ago.
