Crypto Options Basics

TL;DR. An option is a contract that gives you the right, but not the obligation, to buy (a call) or sell (a put) an asset at a set price before a set date. You pay a premium for that right. Options let you express more precise views than simply being long or short — but they add moving parts that punish guesswork.

What an option is​

When you buy a perpetual future, your profit moves more or less one-for-one with price. An option is different: you are buying a choice. A call is the right to buy at a fixed price (the strike); a put is the right to sell at a fixed price. You pay for that choice up front — the premium — and the most you can lose as a buyer is what you paid.

Why options exist​

Options let traders do things a simple long or short cannot:

  • Hedge an existing position against a sharp move.
  • Express a view on volatility itself — whether the market will be calm or wild — not just on direction.
  • Define risk in advance, since a bought option has a known maximum loss.

Where this track is going​

This section builds up from here:

  • The Greeks — how an option's price reacts to price, time, and volatility.
  • Implied volatility and skew — what the market is pricing in.
  • Max pain — a widely-watched options-derived level.
  • Options vs perps, and using options to hedge a scalping book.
