Client Stories

Testimonials

We booked the BTC Hardware Assessment before signing a lease addendum for extra rack space. The report showed one unit throttling at 38°C intake — landlord paid for duct extension after seeing the thermal photos.

— Yeon-woo C., 14-rig farm, Incheon Nam-gu

The sourcing session narrowed six broker quotes to two legitimate paths. I still waited three weeks for delivery, but avoided a PSU mismatch that would have fried two boards.

— Marcus T., first-time buyer, Seoul

Audit team was punctual and did not oversell fixes. They could not reach our roof exhaust and said so plainly — saved us from paying for a full redesign when only internal baffles were needed.

— Hye-jin R., hosting operator, Ansan

Report language was clear enough to forward to our accountant for capex documentation. Turnaround was six days, not five, because of Chuseok — they warned us at booking.

— Dong-min S., family operation, Bucheon

Case note: Songdo warehouse expansion

A client planned to add eight S19-class units to an existing 0.4 PH/s row. Our on-site audit found uneven intake across the north wall — three units were recycling hot air from the exhaust lane. Recommended baffle placement cost less than ₩2,000,000 in metalwork; recovered hash paid back the audit fee within six weeks at their power rate.

We documented before/after pool screenshots with timestamps redacted at client request. Full write-up available on request during a consultation.

Case note: Refurbished batch in Seo-gu

A refurbished import of four units flagged 7–11% hash deficit in lab burn-in. Two hash boards failed within the first 12 hours; client used our serial-level notes to negotiate partial credit with the broker. Assessment fee was ₩760,000 per unit under batch pricing.
