Registered Business
Utilitysycamore Mining Review Co., Ltd. is the official registered business name of this company. We were established in 2019 in Busan, South Korea, to fill a gap between large-scale mining consultancies and informal online hardware forums.
How We Started
Founder Min-jun Chae spent four years maintaining GPU rigs at a small co-location facility in Gijang before recognising that most operators in the 0.05–5 TH/s per-unit range had nowhere to turn for honest hardware comparisons and on-site commissioning. Utilitysycamore began as a two-person workshop reviewing used ASIC batches for local buyers. By 2021 we added electrical assessment and procurement coordination as single-site yards multiplied along the southern coast.
What We Do Today
We remain focused on mid-range equipment — units rated at 0.05 TH/s and above that a single operator can manage from one yard. Our Busan office houses a testing bench where incoming hardware is hash-rate verified before shipment to client sites. We do not sell hash rate, operate pools, or manage remote fleets.
Our Team
- Min-jun Chae — Founder, lead hardware evaluator. Former co-location technician with ASIC repair certification from Bitmain’s Seoul service partner.
- So-yeon Park — Electrical planning lead. Licensed electrician with eight years of commercial panel work in Gyeongsang province.
- Dae-hyun Kim — Commissioning field lead. Oversees on-site installation crews and produces post-deployment thermal reports.
- Hye-jin Lee — Client coordination. Manages scheduling, vendor communications, and written deliverables.
Working Approach
We visit your site before recommending hardware. Every procurement shortlist includes watt-per-TH figures measured on our bench, not manufacturer spec sheets alone. We document what we find — including shortcomings — because a yard that overheats in August costs more than any commission we earn.
Values
- Independence — We accept no referral fees from hardware vendors. Recommendations follow measured performance data.
- Transparency — Quotes itemise advisory fees, travel, and commissioning days separately from hardware purchase costs.
- Local presence — Our crew operates from Busan and serves single-site yards across South Korea, with priority response in Gyeongsang and Jeolla regions.
Community
We sponsor quarterly meetups at our Demo-ro office where operators share cooling setups and power-contract lessons. Attendance is free for active clients and open to prospective operators by registration through our contact form.
