Options are contracts that give you the right, but not the obligation, to buy or sell an asset at a set price before a set date.
Call vs Put
| Option | Right To | Bullish or Bearish |
|---|---|---|
| Call | Buy at strike price | Bullish (price goes up) |
| Put | Sell at strike price | Bearish (price goes down) |
Key Terms
| Term | Meaning |
|---|---|
| Strike price | Price at which you can buy/sell |
| Expiry | When the option expires |
| Premium | Cost of the option |
| In the money (ITM) | Option has intrinsic value |
| At the money (ATM) | Strike ≈ current price |
| Out of the money (OTM) | Option has no intrinsic value |

Risks
| Risk | Explanation |
|---|---|
| Theta decay | Options lose value daily |
| Expiry | Worthless if wrong direction |
| Low liquidity | Wide spreads on some exchanges |
| Complexity | Easy to misprice options |
Bottom Line
Options are powerful but complex. Start with simple long calls or puts on Deribit or Binance. Never sell options until you fully understand the risks. Theta decay means options are a depreciating asset — timing matters as much as direction.
Where beginners go wrong with options
Options look appealing because they promise defined risk — you can only lose the premium on a long call or put — but that defined risk comes with its own trap: theta decay. Every option loses value as time passes, so buying an option and being right about the direction is not enough. If the price moves the right way too slowly, or stays flat, the option can still expire worthless. Many beginners buy an option, watch the market eventually move in their favour, and are surprised to find their option already decayed to zero because the move came late.
A second common error is underestimating the asymmetry between buying and selling. The marketing around options often emphasises the capped loss of buying, but selling an option collects a small premium while taking on large or unlimited risk. Writing an uncovered call or put can lose far more than the premium received, which is why the seller’s side is genuinely dangerous for newcomers. The gone are the days when anyone could assume selling is safe “income” — a big adverse move can erase the premium and then some.
Liquidity is the final stumbling block. Traditional options have deep, liquid markets, but crypto option liquidity is only moderate and varies by exchange and strike. On a thinly traded chain you can face wide spreads that silently eat into any edge. The practical advice is to start on the more liquid centralised venues like Deribit or Binance, stick to the main BTC and ETH expiries, and use simple long calls or puts rather than exotic combinations until you have real experience.
A realistic starting plan
If you want to dip into crypto options, keep the first trades deliberately simple. Buy a long call if you expect a rise or a long put if you expect a fall, size the position so that losing the entire premium is acceptable, and choose an expiry with enough time for your thesis to play out — buying an option that expires in a few hours is closer to gambling than trading. Because theta works against you every day, a trade that needs a large move quickly is a losing proposition before it starts, so give yourself room and resist the urge to keep doubling into a decaying position.
Set a clear mental budget and a rule for when to walk away. If an option loses most of its value, the disciplined response is to accept it rather than hold and hope, since hope does not stop decay. The more professional approach is to treat the option as one input into a broader risk plan, deciding in advance how much the premium is worth losing and what price or time level would end the trade. Options are powerful and flexible, but they reward planning and punish improvisation, so the structure you bring to the trade matters more than the cleverness of the setup itself.
Common questions about crypto options
Which is better, buying or selling options? For a beginner, buying. A long call or put caps your loss at the premium and is the simplest way to learn how options behave. Selling options collects income but takes on large or unlimited risk, so it should wait until you understand pricing and risk management in depth.
What does in the money, at the money, and out of the money mean? In the money (ITM) means the option has intrinsic value given the current price; at the money (ATM) means the strike is roughly equal to the current price; out of the money (OTM) means the option has no intrinsic value yet. These positions change as the underlying moves.
Do crypto options work differently from traditional options? The mechanics are the same, but crypto options tend to have weekly and monthly expiries alongside quarterly ones, are usually cash-settled, have a centralised exchange or DeFi counterparty rather than a clearing house, and generally have lower liquidity than traditional markets.
