Case Study: BTC China achieves uninterrupted high-volume bitcoin trading during massive DDoS attacks with Incapsula

Incapsula Enables BTC China to Sustain World-Leading Bitcoin Trading Levels Even Under Massive DDoS Attack

BTC China, launched in 2011 as the first Bitcoin exchange in China, grew into the world’s largest digital currency trading platform (≈40,000 BTC/day) and prioritized state‑of‑the‑art security and 99.9% uptime. The company faced daily, high‑volume DDoS attacks—peaking around 100 Gbps—that its existing defenses couldn’t handle, causing downtime during critical trading periods; blackholing, delay pages and CAPTCHA approaches were unacceptable because they disrupted legitimate users and APIs.

BTC China selected Imperva Incapsula’s cloud‑based DDoS protection for its high capacity, always‑on mitigation, non‑intrusive traffic filtering and enterprise WAF. Incapsula scrubbed and blocked massive network and application attacks (including XSS/SQLi and human‑like bots), supported 24x7 SOC monitoring, and kept BTC China’s trading platform available with no noticeable performance degradation—becoming a core part of the exchange’s security infrastructure.
