How Premium Works
Frequently Asked Questions
Is the premium I pay for an option like a deposit that's returned if I don't exercise?
No—this is the most dangerous misconception in options trading. Premium is capital you forfeit at purchase. If you buy a Bitcoin call for $800 and don't exercise before expiry, the $800 is gone permanently. There is no deposit that returns; there is no margin-like funding relationship. The premium is what you paid for the right to buy Bitcoin at a fixed price. If you never exercise and the option expires worthless, you received no benefit and paid $800 for rights you didn't use. This is why option buyers face consistent losses: they treat premium as recoverable deposits rather than capital at risk. Options are capital deployment, not margin borrowing. You would not borrow $800 on margin if the breakeven required Bitcoin to move 15%—yet that's what many options buyers do by purchasing OTM calls with low probability.
Why is the premium for an ATM Bitcoin call more expensive than an OTM call if both expire in 30 days?
The ATM call is more expensive because it has higher probability of profit and higher expected value at expiration. An ATM call with delta ~0.5 has approximately 50% probability of expiring ITM; an OTM call with delta ~0.15 has only 15% probability. The market prices this higher probability into the higher ATM premium. An ATM call for $2,000 premium has expected value roughly $1,000 × 50% probability = $500 expected value. An OTM call for $400 premium with 15% probability has roughly $400 × 15% = $60 expected value. Both are theoretically fair prices if the market is efficient. Cheap OTM premiums feel attractive but reflect low probability. If you buy 5 OTM calls hoping one hits, you've paid $2,000 for expected value of $300. This is why experienced traders prefer ATM or slightly OTM with defined-risk spreads rather than outright OTM buys.
How do I know if the premium I'm paying for a protective put is reasonable?
Compare current IV Rank to historical context. A protective put at IV Rank 15% costing $600 on a $55,000 strike is reasonable insurance—premium is cheap relative to what it costs in other periods. The same put at IV Rank 85% might cost $2,500. Before allocating portfolio capital to insurance, check IV Rank: if it's below 30%, insurance is attractively priced; if above 60%, seriously consider whether the cost is justified or if reducing spot exposure is preferable. As a rule of thumb, annual protective put costs shouldn't exceed 2-4% of portfolio value ($1,000-2,000 annually on a $50,000 portfolio). If premiums are consuming more, either IV is extremely elevated or you're over-insuring. Use IV Rank to time put purchases: buy when IV is low, roll when IV is elevated and you don't need protection.
Common Misconceptions About Premium
If I pay a higher premium for an option, I should get a higher return if I'm right on direction.
Premium paid determines maximum loss, not potential return magnitude. If you pay $2,000 premium on an ATM call versus $400 on an OTM call, and Bitcoin rises 20%, the ATM call profits more in absolute dollars because it started with more intrinsic value. But percentage return isn't higher—it's lower. The $400 OTM call rising from $400 to $800 (if it reaches ITM) is a 100% return. The $2,000 ATM call rising to $5,000 is only a 150% return, not a higher return rate. More importantly, the OTM call is unlikely to double; the ATM call is more likely to profit. Professional traders don't chase highest percentage returns; they match premium cost to probability. Paying more premium for ATM strikes is correct if probability justifies it—not because high premium means high payoff.
I shouldn't buy options because the premium is like throwing money away if Bitcoin doesn't move.
Premium is insurance cost, not money thrown away. A protective put costing $600 that expires worthless did its job—it protected your Bitcoin holdings during that period. Just as home insurance that never requires a claim isn't a waste (it provided security), options premiums that expire worthless provided protection and optionality during their lifetime. However, the misconception contains a valid kernel: buying speculative OTM calls with low probability is poor use of premium. Buying defensive puts at low IV or defined-risk spreads with favorable odds is sound capital allocation. The issue isn't premium cost itself; it's whether the premium-to-probability ratio is justified. Directional calls bought when IV Rank is 75% are poor use of premium. Protective puts bought when IV Rank is 20% are wise insurance.
Premium prices always decrease as an option gets closer to expiry because there's less time value.
Premium decreases if implied volatility stays constant or declines. But if IV expands significantly as expiry approaches, premium can increase despite time decay. Before a Bitcoin halving, as expiry approaches, IV typically rises—offsetting or even overwhelming time decay. A call worth $800 with 30 days to expiry might become $1,200 with 10 days to expiry if IV doubles. The premium component from extrinsic value does decay to zero at expiry, but if IV is rising (vega is positive for long options), the IV gain can exceed the theta loss. Near catalytic events, don't assume premium necessarily decreases—it depends on IV movement. Check both theta decay and vega exposure when managing near-expiry positions.
