While the title seems simple, there is significant ambiguity. First, which specific 'Ethereum Volatility Index' is being referenced? (e.g., Deribit's ETH DVOL or T3 Index's EVI?). Second, what defines 'hit'? Does it mean touching the level at any point during 2026 (intra-year high/low), or the closing value at year-end? Third, '↓ 50' as a single option is confusing. If it means 'Will it drop below 50 at any point', that is extremely likely for volatility indices (often ranging 40-70), making the bet trivial. If it implies 'Will the peak remain below 50?', that is a very different bet. The precise definition of the index source and the trigger condition is critical.
