yes you can earn btc
no you as can not earn btc as cheaply as it is to buy it.  most every where in the world.


First question to you is your power cost cheap (under 10 cents a watt)

second question to you is do you need a space heater?

If you need a space heater and your power cost is cheap you can buy a 1 board modded s19 xp miner

Maybe 600 bucks  it mines 35 th or $1.75 a day

since you need a space heater you do not mind the power it burns.
