Who pays us, for what, and what it changes for you.
Some links on this site are affiliate links. If you sign up through one, the platform pays us a commission. It costs you nothing extra.
Ad — affiliate link. We are paid a commission if you sign up. It costs you nothing extra.
Every affiliate link in a lesson carries a mark immediately after it:
Deribitad
The mark is applied automatically rather than by hand, so an unmarked affiliate link cannot exist on this site. The links also carry a rel="sponsored" attribute.
Options and futures exchange. Used throughout the course as the options example.
Where in the course: Modules 5, 6, 7
Options are a complex instrument. The course teaches them as a hedging tool, not as speculation.
Solana DEX aggregator and lending platform (Jupiter Lend).
Where in the course: Modules 1, 3
Jupiter Lend uses rehypothecation — this is taught explicitly in lesson 3-6.
A bank with built-in crypto trading and a separate Revolut X exchange.
Where in the course: Module 1
The course states plainly that buying small amounts in the Revolut app is expensive. The partnership does not change that.

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
CUj6wYQLSBxidzm7Lqtkxbw2d8Sv2H2tbJELyAjR756MSolana 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.
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.
