Partner banks of cryptocurrency exchanges are facing a concerning rise in fraudulent accounts. According to reports, KB Kookmin Bank, which partnered with Bithumb, experienced a sharp increase in accounts linked to financial fraud starting in April. The number jumped from around 100 in January-February to 268 in April. This increase raises concerns about the effectiveness of current fraud prevention measures within the cryptocurrency ecosystem. Stricter KYC (Know Your Customer) and AML (Anti-Money Laundering) protocols are crucial to combat this trend. Interestingly, NH Nonghyup Bank, Bithumb's previous partner, saw a decrease in fraudulent accounts after KB Kookmin Bank took over. In June, they reported only 68 fraudulent accounts, suggesting a possible shift in where fraudulent activity is concentrated. This data highlights the dynamic nature of financial crime in the crypto space and the need for constant vigilance. ```
