The Bitcoin options market is experiencing a strong bullish sentiment, with $80,000 call options emerging as the most concentrated bet. Data reveals that the notional open interest for $80,000 call options expiring at the end of June on the Deribit platform has surpassed $1.5 billion, leading all strike prices. Analysts suggest this surge in convexity bets reflects investors' strong expectations for Bitcoin to reach new all-time highs amid the halving effect and ongoing ETF inflows. Concurrently, the rise in implied volatility indicates traders are pricing in significant price swings, increasing the cost for bullish positions.
