Most losses aren’t hacks. They’re avoidable mistakes.
Spectacular hacks fill the headlines — but most real losses happen quietly: a screenshot, a wrong link, a blind confirmation. Meet the classics before you make them. It is the cheapest skill in all of crypto.
The problem
Four ways people actually lose it.
Not one of these is a hack. Press each junction and read two things: what it costs, and whether it can be undone. Watch the second readout while you go.
One route, four junctions
NOTHING PRESSED YETFour junctions, none of them pressed. Start with any one.
Four losses, and not one of them needed an attacker to be clever. A photo that synced on its own, a balance somebody else held the keys to, a confirmation that was read too fast, an address that was correct in the wrong place. That is what the headline number hides: most losses are avoidable mistakes, not hacks — and almost every one of them is 100% avoidable.
“If I send to a wrong address or over the wrong network, support can reverse it.” No. Crypto transactions are final in many cases, and no central party can pull back a correctly signed transaction. The checks all live before you press send: check the address, check the network, and for a larger amount send a small test transaction first.

Hands on
You are stuck and looking for help. Five things happen.
Three of these are attackers arriving. Two are ordinary, genuine help. Pick one, read what actually reaches you, then call it — treating every helper as an attack is its own way to get stuck.
Choose one above, then call it.
Real support solves problems without ever needing your seed or your private key. Anyone who asks for either — in a chat, by email, or through a “help form” — is an attacker, however convincing everything around the request looks. That single rule disarms a huge share of all scam attempts. No exception. Ever. From anyone.
The bridge
Four habits, and none of them is hard.
Each one closes a junction you just pressed. The first is the one people forget.
Knowing the classics is most of not making them. The last lesson of this section takes these four habits and turns them into a system — storage architecture, every-time habits, and a backup you have actually tested — because a rule is easy to forget and a system is not.
