2) Asics being used for heating thus 99.9% of energy being converting into needed product and mining for BTC merely being a product that subsidizes the energy bill
You do understand that ASIC's are very cheap to manufacture once designed and tested and that we are just going through a transitional period
where the 10+ ASIC fabs are recouping initial capital investment costs right?
I just looked up a random ASIC, it consumes 1350W and costs 2500$. If you would buy an electric heater, you could get one for 50$. ASICS produce heat, but are not made for heating. I get that its a "win-win" on paper.
Not only expensive, but the PCB inside can release some nasty stuff, so it is not advised to use it as heating. There is another thread discussing uses of old ASICs, most common being a doorstop in your house.
Regarding the tx "fee" of ~85 kWh/tx, its the miners (or the network if you like) who pay it. They are "wasting" 90% of the electricity to solve a puzzle with a computer and that is Bitcoin. They are compensated for the wasted electricity with the payout of 25BTC/block and hence still make a profit.
It's not the Bitcoin user who pays this fee in any way. Its a resource used by the miners to create a product.
