🎡 What is the Wheel Strategy? ▼

The Wheel strategy is a method of earning passive income by repeatedly selling options, ideal for investors who are long-term bullish on BTC.

  • Step 1 (Have USDT): Sell Put options below current price, collect premium
  • If assigned: Buy BTC at strike (cheaper than expected), plus you already collected premium
  • Hold BTC: Sell Call options above current price, keep collecting premium
  • If assigned: Sell BTC at strike (higher than expected), profit, back to USDT

Core idea: You earn premium at every step regardless of direction. The main risk is if BTC drops sharply, unrealized losses on BTC holdings may exceed premium income.

💛 Sell Put Explained (When Holding USDT) ▼

Selling a put option: You sell someone the right to sell you BTC at the strike price before expiry.

📌 Example: BTC current price $80,000
You sell a Put with strike $75,000, 14 days to expiry
Premium received: $400

Scenario 1 (BTC at expiry > $75,000): Option expires worthless ✅ You keep $400
Scenario 2 (BTC at expiry = $73,000): You must buy at $75,000
  Actual cost = $75,000 - $400 = $74,600
  Paper loss: $73,000 - $74,600 = -$1,600
  • Max profit: Premium (BTC stays above strike)
  • Max loss: Strike × contracts (BTC drops to 0, extreme case)
  • Tip: Choose strike 10-20% below current price, Delta around -0.20
💜 Covered Call Explained (When Holding BTC) ▼

Covered call: While holding BTC, sell Call options above current price, using your holdings as collateral.

📌 Example: You hold 1 BTC, current price $80,000
You sell a Call with strike $90,000, 21 days to expiry
Premium received: $600

Scenario 1 (BTC at expiry < $90,000): Option expires worthless ✅ You keep $600, still hold BTC
Scenario 2 (BTC at expiry = $95,000): You must sell at $90,000
  Actual sale price = $90,000 + $600 = $90,600
  You miss $95,000 but earned $600 more than just holding
  • Max profit: (Strike - entry cost) × contracts + premium
  • Main risk: BTC crashes, premium doesn't cover holding losses
  • Tip: Choose strike 10-20% above current price, Delta around 0.20
📊 Understanding Delta / IV / IVP ▼
  • Delta (-1 to 0 / 0 to 1): Reflects assignment probability. Put Delta -0.20 means ~20% chance of assignment. Closer to 0 = safer, lower returns.
  • IV (Implied Volatility): Market's expected BTC volatility. Higher IV = more expensive options = higher seller returns.
  • DVOL: Deribit's BTC volatility index, similar to stock market VIX. Below 50 is low, above 80 is high.
  • IVP (IV Percentile): Where current DVOL ranks over the past year. IVP > 70 means vol is historically high — good time to sell options.
  • Theta: Daily time decay of option value. As a seller, Theta is your friend — it earns you money every day.
