Every option has a breakeven price you must pass by expiration to be profitable: Call breakeven = strike price + premium Put breakeven = strike price - premium

BTC is trading at 40,000 USD. 40,000 USD call: higher cost, higher probability of profit 45,000 USD call: lower cost, needs a bigger move in price to pay off Both are bullish, but with very different risk and profitability profiles.

Allowing too little time: the trade expires before the anticipated price move Paying too much for time: returns don’t exceed the premium Ignoring decay: the value of the option drops even if price is flat

Choosing a strike price and expiration date

Q: Choosing an expiration date

Longer expiration Shorter expiration Premium Higher Lower Time for your view More time for your view to play out Requires faster price movement Sensitivity Less sensitivity to short-term moves More sensitive to timing What changes with time Options lose value as time passes (time decay). Short-dated options lose value fastest, especially in the final days before expiration.

Q: Match time to your view

Expect a move soon: pick a closer expiration date Expect a slower trend: select a farther expiration date Unsure on timing: allow more time

Your strike price sets the trade-off between cost, probability and payoff. Time affects both cost and how precise your view needs to be.

Choosing a strike price

A quick reminder on moneyness: at the money (ATM) means the strike price sits at or near the current price of the underlying, while out of the money (OTM) means it sits further away in the unfavorable direction (above current price for calls, below for puts).

	Closer to current price (ATM or near-ATM)	Farther from current price (OTM)
Premium	Higher	Lower
Probability of profit	Higher	Lower
Returns	Lower percentage returns	Higher potential returns

What you’re really choosing

You pay more for higher probability or less for higher profit potential. There’s no “best” strike price, only the one that fits your view.

Breakeven price

Every option has a breakeven price you must pass by expiration to be profitable:

Call breakeven = strike price + premium
Put breakeven = strike price - premium

Strike price example

BTC is trading at 40,000 USD.

40,000 USD call: higher cost, higher probability of profit
45,000 USD call: lower cost, needs a bigger move in price to pay off

Both are bullish, but with very different risk and profitability profiles.

Choosing an expiration date

	Longer expiration	Shorter expiration
Premium	Higher	Lower
Time for your view	More time for your view to play out	Requires faster price movement
Sensitivity	Less sensitivity to short-term moves	More sensitive to timing

What changes with time

Options lose value as time passes (time decay). Short-dated options lose value fastest, especially in the final days before expiration.

Match time to your view

Expect a move soon: pick a closer expiration date
Expect a slower trend: select a farther expiration date
Unsure on timing: allow more time

Common mistakes

Allowing too little time: the trade expires before the anticipated price move
Paying too much for time: returns don’t exceed the premium
Ignoring decay: the value of the option drops even if price is flat
