In August 2021, I invested 1 BTC in acquiring six Antminer S19j Pros, cutting-edge mining rigs priced at $7,500 each. These were set up with Compass Mining, tapping into affordable electricity at $0.06 kw/h, later increasing to $0.08 kw/h. However, the profitability dwindled rapidly, with the miners now valued at $500 each, resulting in a loss of 0.95 BTC on hardware. Over three years, despite mining 0.9 BTC, 0.7 BTC was consumed by electricity costs, leaving just 0.2 BTC in profit. Ultimately, my initial 1 BTC investment yielded a mere 0.25 BTC, marking a staggering 75% loss. This cautionary tale underscores the futility of mining compared to simply holding bitcoin. While companies may profit through fiat loans for mining equipment, direct bitcoin investment in hardware leads to perpetual depreciation, nullifying any potential gains. Presently, the Antminer S21 demands 0.09 BTC and generates a monthly return of 0.001-0.002 BTC after expenses, with a break-even period of 4-7 years, rendering recouping bitcoin virtually impossible.#altcoins #BinanceLaunchpool #BTC #MicroStrategy #bitcoinhalving
