About Us

Registered Business

Sitecypressfield Mining Review Co., Ltd. is the official registered business name under which we operate. We were established in 2019 in Daejeon, South Korea, after our founders spent several years maintaining rack installations for small and mid-size mining operators who lacked access to impartial equipment assessments.

How We Started

The company began when two former facility technicians — one from a Chungcheong data-centre maintenance crew, the other from a hardware resale shop — kept receiving the same question from operators: “Will this unit actually hold 0.05 TH/s on my half-rack shelf?” Manufacturer spec sheets rarely accounted for cramped rear clearance or shared PDU circuits. We started writing structured shelf reports as a side practice, and by late 2019 the volume justified a dedicated office on Test-daero in Jung-gu.

What We Do Today

We visit facilities, bench-test individual units, and produce written assessments that cover hash-rate stability, thermal behaviour, acoustic output, and physical fit within compact rack shelves. We do not sell hardware, take commissions from manufacturers, or operate mining pools. Our income comes solely from review and consultation fees.

Our Team

Jae-ho Park — Lead Reviewer. Fifteen years in electrical maintenance, certified in industrial thermal imaging. Conducts on-site rack audits.

So-yeon Choi — Bench Test Specialist. Former ASIC repair technician. Runs our Daejeon bench lab where units are stress-tested before shelf installation.

Dong-wook Lim — Report Editor & Client Liaison. Translates raw measurement data into plain-language reports and coordinates visit scheduling across Chungcheong province.

Working Approach

We arrive with our own instruments — clamp meters, infrared thermometers, sound-level meters, and calibrated hash-rate logging software. Every assessment follows the same core checklist, but we adjust depth based on your shelf configuration and the number of units under review. We photograph each U-position, note cable routing, and record ambient temperature at intake and exhaust.

Values

Accuracy over optimism. If a unit falls below its rated hash-rate on a realistic shelf setup, we say so. Operators deserve numbers they can plan around, not marketing copy repackaged as advice.
