ASIC miners

In plain words

An ASIC miner is the whole machine: boards of mining chips, a heavy power supply, fans that never rest. A modern unit draws the power of several space heaters, around the clock, and roars like a vacuum. This is industry, not furniture. Home mining survives where electricity is cheap — or where the heat itself is put to work.

Why it matters

• The physical layer of Bitcoin's security — someone, somewhere, runs these.
• Electricity price decides everything; the hardware is secondary.
• New chips retire old machines in a few years. The treadmill spares no one.

Not to be confused with

• Node hardware — checking Bitcoin takes a quiet mini-PC, not one of these.
