Learning paths

Pick a path by your question

The course has 76 lessons — but you do not need all of them. A path is a curated sequence of 7–8 lessons answering one specific question. Same lessons, just selected and ordered in a way that works.

I want to buy my first crypto without making an irreversible mistake

„I have my first few hundred euros. How do I buy crypto, move it to my own wallet, and not get lost between ten different apps?“

I want to accumulate slowly and have a rule for when to sell

„I do not want to trade or watch charts. How do I buy a little at a time, stop worrying about the price, and know in advance what I will do when it goes up or down?“

I need cash but I do not want to sell my SOL

„I need liquid money and I do not want to sell my SOL. Is there another route, and how risky is it?“

I want to understand how providing liquidity actually works

„Everyone talks about “passive income” from liquidity pools. How does it actually work, and where is the cost nobody mentions?“

I am afraid of a deep drop and want to hedge without selling

„What if it falls 40% tomorrow? Can I insure that the way I insure a house — without selling the house itself?“

Free material is easy to put off

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.

Solana address

CUj6wYQLSBxidzm7Lqtkxbw2d8Sv2H2tbJELyAjR756M

Solana network only

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.

What you get for it

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.

Where the money goes

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.
