Self-custody, without the slogans
"Not your keys, not your coins" is repeated constantly and explained almost never. Here is what the sentence actually refers to, and what taking it seriously costs you in daily practice.
Education, not advice
Most crypto writing is either selling you something or warning you off. Neither explains the machine.
This site does one thing: describe how custody, wallets and transaction security actually work, in enough detail that you can make your own decisions and spot when someone is misleading you.
Start here
Four explainers and a glossary. Read them in order if you are new; the glossary is written to be used as a reference rather than read straight through.
Foundations
How a wallet actually works, and what a wallet is not
The word is a bad metaphor. A wallet holds nothing. Understanding what it does hold removes a whole category of confusion about backups, recovery and what happens when a device breaks.
Security
Seven scam patterns, and the structural tell in each
Naming specific scams is useless — they rename themselves weekly. The underlying structures are few and stable, and each has a giveaway that does not depend on knowing the brand.
Practical
Records before you need them
Reconstructing years of activity after the fact is the single most tedious job in this field, and it is entirely avoidable. What to record, when, and why exports are not enough.
Reference
A working glossary
Definitions written against how terms are actually used, including where common usage is wrong. Meant for looking things up, not reading through.
What this site will not do
It will not tell you what to buy, when to buy it, or what anything will be worth. Not out of caution — because nobody who writes that knows it either, and the ones who claim to are describing a bet as if it were a forecast.
It also sells nothing. There is no course, no signal group, no referral link to an exchange, and no affiliate arrangement anywhere on this site. That is worth stating plainly because in this subject the financing model usually explains the content.
What it does instead
Explains the mechanisms. A surprising amount of loss in this space comes from misunderstanding something structural — what a seed phrase actually is, what an exchange balance actually represents, what happens when you approve a contract. Those are learnable in an afternoon, and knowing them removes an entire class of expensive mistakes.
The single most useful thing to internalise: a balance shown by an exchange is an entry in that company's database saying they owe you something. A balance controlled by keys you hold is different in kind, not in degree. Almost every large loss of the last decade sits on one side of that line. The full explanation is in self-custody.
Who writes this
The operator is stated in full in the imprint. We hold positions in crypto-assets; that is precisely why nothing here recommends one. Where a claim is contested we say so rather than picking the version that reads better.
