“They caught that my wall meter was reading higher than the PSU sticker. Once we used the real draw, the ‘profitable’ dual-GPU plan dropped below break-even at my Kwun Tong rate.”
— Marcus L., dual RTX desk, Kowloon · Profitability assessment
“I wanted a second opinion before ordering used cards from a forum. The write-up was careful about difficulty drift; I still bought one card, not three. Turnaround on the PDF was a day later than hoped after Chinese New Year, but the content was worth the wait.”
— Aisha R., first-time home miner, Mid-Levels · Profitability assessment
“Hashrate verification showed my undervolt had drifted after a driver update. Power went up twelve watts for almost no MH/s. Small fix, clearer bill.”
— Ken W., single-card evening miner, Tsuen Wan · Hashrate & power verification
“Hardware review talked me out of a bargain PSU that sat under continuous load. Dry advice — which I needed.”
— Priya S., upgrade planning, Sai Ying Pun · Hardware configuration review
Extended note — the quiet rack that stayed quiet
A Sheung Wan client brought three candidate cards and a shared-flat constraint: noise after 11 p.m. and a meter that already carried air-con. In the profitability assessment we modelled each card at 70% evening uptime (their realistic window) rather than 24/7 forum defaults. Only one configuration stayed slightly positive after pool fees; the other two looked fine on a 24-hour spreadsheet and failed once night limits applied. They bought the quieter card, skipped the “deal” pair, and asked us to re-check after thirty days of pool data — the verification session confirmed wattage within 4% of estimate.
