Risk Factors

• BNB deemed a security by SEC or court could force trust termination
• Staking condition may never be satisfied, eliminating yield advantage vs direct BNB holding
• Extreme BNB price volatility and concentrated ownership (top 100 wallets ~82%)
• Limited in-kind creation/redemption capability may impair arbitrage mechanism
• Custodian liability capped at $150M per cold storage address; trust assets may exceed this threshold
• DCG (parent) holds minority stake in Kraken (Index constituent), creating potential conflict of interest
