What I learned, and how I learned it.

Personal write-ups from the messy middle — confused afternoons, wrong assumptions, and the maps I drew after things finally clicked. For the straight explanation, read the guides.

Looking for how something works without the story? The guides are summarized and straight to the point.

Nº 01 · 13 June 2026

I moved my coins and had no idea what happened.

A complete beginner's map of one confusing afternoon on Hyperliquid — and the two machines quietly hiding behind the word "trade."

Nº 10 · 12 June 2026 Medium risk

My stETH was worth less than ETH and nobody warned me.

Liquid staking tokens are sold as "basically ETH" until they aren't — what an LST depeg is and why it shows up when things break.

Nº 06 · 11 June 2026 High risk

Yield farming — the slot machine wearing a spreadsheet.

Liquidity pools, reward tokens, impermanent loss, and why the APY on screen is always the best-case story.

Nº 09 · 10 June 2026

I connected my wallet and hoped that was enough.

dApps looked like normal websites until I learned what actually happens when you click "Connect wallet" — and what still can't touch your money.

Nº 08 · 9 June 2026

I sent crypto to the wrong network and panicked.

Mainnet, Layer 2, sidechains — I treated them like folders in one account until a failed transfer taught me they're separate worlds.

Nº 05 · 8 June 2026 Medium risk

Lending and borrowing — the bank window, without the bank.

How DeFi lending pools work, why people borrow against their own crypto, and the liquidation cliff nobody demos in the tutorial.

Nº 04 · 5 June 2026 Low risk

Staking — getting paid to sit still (sort of).

What it means to lock up crypto for network rewards, why exchanges make it look effortless, and where the risks actually hide.

Nº 11 · 4 June 2026 Low risk

I paid $40 to move $80 and called it learning.

Gas fees made no sense until I stopped treating them like bank charges — and started seeing them as bids for space in a shared computer.

Nº 03 · 3 June 2026 Low risk

Hardware wallets — the offline safe I should've bought sooner.

What a hardware wallet actually does, when you need one, and why "not your keys, not your coins" isn't just a T-shirt slogan.

Nº 02 · 1 June 2026 Low risk

Buying your first crypto without pretending you know what you're doing.

How regulated exchanges work, what "verification" is actually for, and why your first purchase should be boring on purpose.

Nº 07 · 30 May 2026

Everyone said EVM like I was supposed to know.

I nodded along for months before learning the EVM is just a shared computer — and why that one sentence unlocks half of DeFi.
