Options Fundamentals
Options are powerful derivatives that give you leverage, defined risk, and the ability to profit from volatility itself—not just direction. Understanding options unlocks trading strategies impossible with spot or perpetuals.
Call vs Put Options
Call Option
- • Right to BUY at strike price
- • Profit when price goes UP
- • Max loss = premium paid
- • Unlimited upside potential
Put Option
- • Right to SELL at strike price
- • Profit when price goes DOWN
- • Max loss = premium paid
- • Profit capped at strike - 0
Key Insight
Options have two value components: Intrinsic Value (how much ITM) + Time Value (premium for time remaining). An ATM option is all time value. Time value decays to zero at expiration—this is theta decay.
Understanding the Greeks
Greeks measure how option prices change with different variables. Mastering Greeks is essential for risk management and strategy design.
Delta (Δ)
How much option price changes per $1 move in underlying. Delta of 0.5 means option gains $0.50 for every $1 BTC rises.
Gamma (Γ)
Rate of delta change. High gamma means delta changes rapidly with price moves. ATM options have highest gamma.
Theta (Θ)
Time decay per day. Options lose value as expiration approaches. Theta accelerates in final days. Theta of -50 means losing $50/day.
Vega (ν)
Sensitivity to implied volatility. Vega of 100 means option gains $100 for every 1% IV increase. Longer-dated options have higher vega.
Implied vs Realized Volatility
The IV-RV spread is the core edge in options trading. Understanding this relationship is crucial for profitable strategies.
Volatility Comparison
Implied Volatility (IV)
- • Market's expectation of future vol
- • Derived from option prices
- • Forward-looking
- • Drives option premiums
Realized Volatility (RV)
- • Actual historical volatility
- • Measured from price data
- • Backward-looking
- • What actually happened
Trading the IV-RV Spread
Options Strategies
Bullish Strategies
Long Call: Simple bullish bet with defined risk. Max loss = premium.
Bull Call Spread: Buy lower strike call, sell higher strike. Cheaper but capped upside.
Cash-Secured Put: Sell put on asset you want to own. Collect premium or buy at discount.
Bearish Strategies
Long Put: Simple bearish bet. Profits when price drops.
Bear Put Spread: Buy higher strike put, sell lower strike. Defined risk/reward.
Protective Put: Own spot + buy put = hedged downside, unlimited upside.
Neutral/Volatility Strategies
Straddle: Buy ATM call + put. Profit from big moves either direction.
Strangle: Buy OTM call + put. Cheaper than straddle, needs bigger move.
Iron Condor: Sell strangle, buy further OTM protection. Profit if price stays in range.

Frequently Asked Questions
A crypto option is a derivative contract giving you the right (not obligation) to buy (call) or sell (put) crypto at a specific price (strike) before expiration. You pay a premium for this right. Options let you profit from price moves, hedge positions, or generate income.
Greeks measure option sensitivity: Delta = price sensitivity to underlying, Gamma = rate of delta change, Theta = time decay per day, Vega = sensitivity to implied volatility, Rho = sensitivity to interest rates. Understanding Greeks is essential for managing option positions.
Deribit dominates with 90%+ market share for BTC/ETH options. Other venues include OKX, Bybit, and Binance. For DeFi options, check Lyra, Dopex, and Premia. Deribit has the most liquidity and tightest spreads for serious traders.
Implied Volatility (IV) is what the market expects future volatility to be—it's priced into options. Realized Volatility (RV) is actual historical volatility. When IV > RV, options are 'expensive'; when IV < RV, they're 'cheap'. This spread creates opportunities.
Popular strategies: Long calls/puts for directional bets, covered calls for income, protective puts for hedging, straddles/strangles for volatility, vertical spreads for defined risk, and iron condors for range-bound markets. Start simple before complex strategies.
