**What Is a Bull Call Spread?**
-------------------------------

A **Bull Call Spread** combines:

1.  **Buy** a lower strike call (e.g., ATM)
    
2.  **Sell** a higher strike call (e.g., OTM)
    

**Result**: Lower net cost than buying a call alone, with capped upside.

**Structure**:

Buy: 10 ETH calls at $3,000 strike

Sell: 10 ETH calls at $3,300 strike (10% OTM)

Net Cost: Premium paid - Premium received

**Why it works**: Selling the higher strike call reduces upfront cost but limits profit above that strike.

* * *

**How Bull Call Spread Works**
------------------------------

### **The Mechanics**

**Step 1: Buy Lower Strike Call**

*   Provides upside exposure
    

*   Premium paid upfront
    

**Step 2: Sell Higher Strike Call**

*   Offsets some premium cost
    

*   Caps maximum profit
    

*   Requires collateral (covered call)
    

**Net Effect**:

*   Lower upfront cost than buying a call alone
    

*   Profit zone between the two strikes
    

*   Maximum profit = spread width - net cost
    

*   Maximum loss = net cost
    

### **Visual Breakdown**

Current ETH Price: $3,000

Buy 10 Calls @ $3,000: Pay $80/ETH = $800

Sell 10 Calls @ $3,300: Receive $40/ETH = $400

Net Cost: $800 - $400 = $400

Maximum Profit: ($3,300 - $3,000) × 10 - $400 = $2,600

Maximum Loss: $400 (if ETH stays below $3,000)

* * *

**When to Use Bull Call Spread**
--------------------------------

### **Ideal Scenarios**

*   Expect a move up, but not extreme
    

*   Want to reduce cost vs. buying calls
    
*   **Budget Constraints**
    

*   Lower upfront cost
    

*   Better capital efficiency
    
*   **Defined Profit Target**
    

*   Comfortable capping upside
    

*   Prefer cost reduction over unlimited upside
    
*   **Volatility Concerns**
    

*   Lower cost reduces time decay impact
    

*   More forgiving if price moves slowly
    

### **When NOT to Use**

*   **Extremely Bullish**: Use a straight call for unlimited upside
    

*   **Neutral/Bearish**: Not suitable
    

*   **High Volatility Expected**: May prefer a straight call
    

* * *

**Bull Call Spread Payoff Scenarios**
-------------------------------------

**Setup**:

*   Current ETH: $3,000
    

*   Buy: 10 ETH calls at $3,000 strike (ATM)
    

*   Sell: 10 ETH calls at $3,300 strike (10% OTM)
    

*   Duration: 7 days
    

*   Premium paid: $80 per ETH = $800
    

*   Premium received: $40 per ETH = $400
    

*   **Net Cost: $400**
    

### **Scenario 1: ETH Drops to $2,700 (-10%)**

**Lower Strike Call ($3,000)**:

*   Expires worthless
    

*   Loss: $800
    

**Higher Strike Call ($3,300)**:

*   Expires worthless (no exercise)
    

*   Premium kept: $400
    

**Net Result**:

*   Loss: $800 - $400 = **\-$400**
    

*   ROI: **\-100%**
    

*   Maximum loss = net cost
    

* * *

### **Scenario 2: ETH Stays at $3,000 (0%)**

**Lower Strike Call ($3,000)**:

*   At strike, no intrinsic value
    

*   Loss: $800
    

**Higher Strike Call ($3,300)**:

*   Expires worthless
    

*   Premium kept: $400
    

**Net Result**:

*   Loss: $800 - $400 = **\-$400**
    

*   ROI: **\-100%**
    

* * *

### **Scenario 3: ETH Rises to $3,150 (+5%)**

**Lower Strike Call ($3,000)**:

*   Profit: ($3,150 - $3,000) × 10 = $1,500
    

*   Premium paid: -$800
    

*   Net: +$700
    

**Higher Strike Call ($3,300)**:

*   Expires worthless
    

*   Premium kept: $400
    

**Net Result**:

*   Profit: $700 + $400 = **+$1,100**
    

*   ROI: **275%**
    

* * *

### **Scenario 4: ETH Rises to $3,300 (+10%) — Maximum Profit**

**Lower Strike Call ($3,000)**:

*   Profit: ($3,300 - $3,000) × 10 = $3,000
    

*   Premium paid: -$800
    

*   Net: +$2,200
    

**Higher Strike Call ($3,300)**:

*   At strike, no exercise
    

*   Premium kept: $400
    

**Net Result**:

*   Profit: $2,200 + $400 = **+$2,600**
    

*   ROI: **650%**
    

*   **Maximum profit achieved**
    

* * *

### **Scenario 5: ETH Rises to $3,600 (+20%)**

**Lower Strike Call ($3,000)**:

*   Profit: ($3,600 - $3,000) × 10 = $6,000
    

*   Premium paid: -$800
    

*   Net: +$5,200
    

**Higher Strike Call ($3,300)**:

*   Exercised against you
    

*   Loss: ($3,600 - $3,300) × 10 = -$3,000
    

*   Premium received: +$400
    

*   Net: -$2,600
    

**Net Result**:

*   Profit: $5,200 - $2,600 = **+$2,600**
    

*   ROI: **650%**
    

*   **Profit capped at maximum**
    

* * *

**Comparison: Bull Call Spread vs. Buying Calls Directly**
----------------------------------------------------------

### **Scenario: ETH Rises to $3,300 (+10%)**

**Option A: Buy 10 Calls at $3,000**

*   Premium: $800
    

*   Profit: ($3,300 - $3,000) × 10 = $3,000
    

*   Net: $3,000 - $800 = **+$2,200**
    

*   ROI: **275%**
    

**Option B: Bull Call Spread**

*   Net Cost: $400
    

*   Profit: **+$2,600**
    

*   ROI: **650%**
    

**Comparison**:

*   **2.4x higher ROI** with Bull Call Spread
    

*   **50% less capital** required
    

*   **Capped upside** (vs. unlimited with straight call)
    

### **Scenario: ETH Rises to $3,600 (+20%)**

**Option A: Buy 10 Calls at $3,000**

*   Premium: $800
    

*   Profit: ($3,600 - $3,000) × 10 = $6,000
    

*   Net: $6,000 - $800 = **+$5,200**
    

*   ROI: **650%**
    

**Option B: Bull Call Spread**

*   Net Cost: $400
    

*   Profit: **+$2,600** (capped)
    

*   ROI: **650%**
    

**Comparison**:

*   Straight call outperforms on larger moves
    

*   Bull Call Spread is more capital efficient on moderate moves
    

* * *

**Risk Considerations**
-----------------------

### **Maximum Loss**

**Maximum Loss = Net Premium Paid**

In our example:

*   Net cost: $400
    

*   Maximum loss: **$400** (if ETH stays at or below $3,000)
    

**Defined risk**: Loss is limited to net premium.

### **Maximum Profit**

**Maximum Profit = Spread Width - Net Cost**

In our example:

*   Spread width: $3,300 - $3,000 = $300 per ETH
    

*   Total spread: $300 × 10 = $3,000
    

*   Net cost: $400
    

*   Maximum profit: $3,000 - $400 = **$2,600**
    

**Capped upside**: Profit cannot exceed this amount.

### **Break-Even Point**

**Break-Even = Lower Strike + Net Cost Per ETH**

In our example:

*   Lower strike: $3,000
    

*   Net cost per ETH: $400 ÷ 10 = $40
    

*   Break-even: $3,000 + $40 = **$3,040**
    

ETH must rise above $3,040 to profit.

### **Time Decay**

*   Both legs are long options (buying)
    

*   Time decay works against the position
    

*   Less impact than a straight call due to lower net cost
    

### **Early Exercise Risk**

*   If the short call is exercised early, you may need to deliver ETH
    

*   Requires collateral management
    

*   On MegaFi, positions are managed automatically
    

* * *

**Advanced Considerations**
---------------------------

### **Strike Selection**

**Tighter Spread** (e.g., $3,000 / $3,150):

*   Lower maximum profit
    

*   Lower net cost
    

*   Higher probability of profit
    

**Wider Spread** (e.g., $3,000 / $3,600):

*   Higher maximum profit
    

*   Higher net cost
    

*   Lower probability of maximum profit
    

### **Duration Selection**

**Shorter Duration** (7 days):

*   Lower premium
    

*   Faster time decay
    

*   Requires quicker price movement
    

**Longer Duration** (30 days):

*   Higher premium
    

*   More time for price to move
    

*   Higher time decay cost
    

### **Rolling the Spread**

If price moves favorably but hasn't reached maximum profit:

*   Close the current spread
    

*   Open a new spread with higher strikes
    

*   Lock in partial profit and maintain exposure
