The Antminer T21 offers strong performance and efficiency at an affordable price, making it a top value choice under $2,000.

Yes, cheaper electricity allows you to run more powerful miners profitably, but efficiency and ROI should still be considered.

Calculate ROI by comparing total costs (miner, power, setup) against expected mining earnings using a mining calculator.

Used miners may have reduced performance, hidden damage, or no warranty, so always verify condition before buying.
