Direction isn't enough — you must clear the premium
Options punish being 'roughly right'. Price has to move past break-even, not just the strike. See the full payoff on the options PnL calculator.
Breakeven is further than the strike
A call is profitable at expiry only above strike plus premium. Buy a $100k BTC call for $3,000 and the coin has to finish above $103,000 before you make a cent. Between $100k and $103k the option lands in the money and you still lose.
Premium is why most bought options expire worthless in profit terms. The market prices volatility fairly well — the strikes that feel like easy wins carry premiums that eat the expected move. Puts mirror it: breakeven is strike minus premium.
Percentage framing keeps it honest. That $3,000 premium on a $103k breakeven means BTC must rise over 3% just to reach zero for you. Compare the implied move to the coin's typical weekly range before buying — when the required move exceeds a normal month of drift, you're paying for a scenario, not a strategy.
