„What if it falls 40% tomorrow? Can I insure that the way I insure a house — without selling the house itself?“
Options are examined here in one sense only — as insurance for a position you already hold. It starts with how much price actually moves, goes through option anatomy, price zones and the Greeks, then the exchange itself, and only then to Puts and Put Spreads. Speculation and earning from options are not part of this path.
Someone who already holds a real SOL or ETH position, understands LTV, and wants to reduce the impact of a drop rather than increase the possible upside.
You will understand how a Put works like an insurance policy, how the strike choice changes both the level of protection and its cost, and why a Put Spread is cheaper but bounded. You will be able to read an options table on the exchange and say what Delta and Theta mean for your position.
Not for you if your position is still small: insurance costs a premium, and that cost is disproportionate on a small position. Not for you if you are looking for a way to earn from options — Covered Calls and premium selling are not taught here. Not for you if you do not yet understand LTV and liquidation — take the collateral path first.
Order matters — each lesson is placed so it builds on the one before it.

Something practice teaches: when you paid nothing to learn, it is easy to postpone learning indefinitely. If these lessons actually gave you something — saved you a mistake, or explained what nobody else did — you can pay whatever you think they were worth.
This is not a price, a subscription, or a fee for access. The amount is yours to choose, and paying nothing is entirely fine.

Send SOL or SPL tokens (e.g. USDC) only on the Solana network. Sending from an exchange over a different network loses the funds permanently — nobody can recover them.
Nothing extra, and that is deliberate. Every lesson, all three difficulty levels and every calculator stay free and sign-up-free, with or without a donation. There is no gated section, no share of profits, no future token and no claim on anything.
A donation becomes my own money. I use it to keep the site running and to fund a public demonstration position on a lending protocol — real money, so the lessons have something to show instead of only theory. I publish the results, losses included, publicly and free for everyone. It is my position and my risk, not a pooled fund.
