Learn this properly, once
Crypto education is mostly people selling you something. These are plain guides to the things that actually cost people money — losing access, buying badly, ignoring liquidity, and forgetting that tax exists. Where we do not know something, we say so.
Getting started
What a crypto wallet actually is
A wallet does not contain coins. Understanding what it does contain explains almost every rule people tell you to follow, and why they are not arbitrary.
Buying your first crypto without getting fleeced
Where to buy, what the spread really costs you, why the first purchase should be deliberately small, and the checks worth doing before you send money anywhere.
Keeping it safe
Why a crypto payment cannot be undone
Card payments can be reversed by someone other than you. Crypto payments cannot. That single difference explains most of the rules, and most of the losses.
The five ways people actually lose crypto
Not hacks of the blockchain — losses come from a short, boring, well-documented list, and each one has a specific defence.
What "not your keys, not your coins" actually means
Who legally holds your crypto, why a private key is the whole asset, and how to decide between an exchange and a device you control.
Researching a coin
What a blockchain actually guarantees — and what it does not
Being on a blockchain proves the ledger was not tampered with. It proves nothing about the project, the team, or whether you will be able to sell.
Can you actually sell it? A short guide to liquidity
The difference between what a holding is worth on paper and what you would receive for it — slippage, depth, sell restrictions, and how to check before you buy.
How to read a coin page without fooling yourself
Market cap, supply, volume and distance from the high — what each number honestly tells you, and the far longer list of things none of them tell you.
Tax and records
When something goes wrong
How to spot a crypto recovery scam
The second loss is usually larger than the first. The tells are consistent, and they are visible before any money changes hands.
You lost access to a wallet. What can actually be done
An honest triage: which kinds of lost access are genuinely recoverable, which are mathematically not, and what to do first in either case.
