"Who's in the market for a sweet deal on some vintage Bitcoin mining hardware? I just scored an OG Antminer S3 (hash rate of 478 KH/s) for a steal and paired it with a L3 (hash rate of 504 MH/s) for a beast of a rig that I think can still make some decent profits. Is anyone else looking to get back into the mining game or upgrade their existing setup?"
