How it works

The whole system, at a glance

The flywheel in plain shapes: what you own goes to work, pays you monthly, and the returns feed back in so it grows itself.

A three-step loop: what you own (Bitcoin, Ethereum, Solana) is put to work through lending, staking and pools, which pays income every month, and the returns feed back in so the system grows itself.
The full flywheel: owned assets (ETH on Base, SOL on Solana) are posted as collateral to borrow USDC conservatively, which funds a productive position (a lending vault or liquidity pool) that earns fees and yield. The proceeds route back by adding collateral, repaying debt or compounding, or are spent as income. A plain lending position with no borrowing is a perfectly good place to stop. Cold-storage Bitcoin and staked ETH run as separate tracks the loop never feeds on.

The risk map

Every part of the flywheel carries one main risk, and each one is met by a rule you write down before you need it. The risks sit side by side, so none of them replaces another. Those rules are the other half of the system, what the book calls calm-day rules.

The eight parts of the flywheel, the main risk in each, and the rule that protects you.
PartThe riskWhat protects you
What you ownThe price falling, or the story you believed in turning out wrong.A written thesis for every asset, one you can still defend when it’s down 40%.
CustodyLosing the coins to theft or a slip.Your own keys and a recovery process, held on your own device.
The protocolThe code, the oracle, or the people behind it failing.Do the research, and keep any one protocol to a size you could stand to lose.
The loanLiquidation.A written limit you act on early, a health factor above 2.0 on Morpho and an LTV in the Safe zone on Jupiter.
The cost of the loanThe borrow rate climbing while you hold.Watch the spread between what you earn and what you pay, and close the gap when it narrows.
The poolImpermanent loss, ending up with more of the side that fell.A pair you’re glad to own on both sides, chosen before you put a dollar in.
The rangeThe price leaving your range, so the fees stop.The wait-or-reset rule you wrote down the day you opened the position.
The advanced layerComplexity you can’t fully see.The strategy bucket, small enough to lose without touching your income.

Underneath all of it, your sealed Bitcoin and your staked ETH sit apart, gaining on their own and touched by none of this.

Tutorials for every hands-on step

Screenshots and short recordings, matched to the chapter that explains why.

You don’t have to do them all. Supplying USDC to a vault, or staking ETH, is a perfectly good place to stop. The borrowing and pool tutorials are here for when you want them.
