How Can You Avoid Fake Crypto Mining Rigs in the Second-Hand Market?
Second-hand ASIC miners are prime targets for scammers. Many buyers end up with counterfeit or tampered rigs. By spotting key red flags early, you can protect your investment.
In my experience selling mining hardware, even seemingly great deals have hidden traps. For example, I once saw a supposedly “new” Antminer S19 offered at half price – until I checked the serial number on Bitmain’s warranty site and discovered it had no valid coverage.
That close call drove home the lesson: always verify every detail.
