How do crypto scams work, and how do you avoid them?
Most crypto losses come from a small number of repeated patterns rather than from exotic hacking. Someone persuades you to reveal a seed phrase or approve a transaction, a project takes deposits and disappears, or a scheme pays early participants with later participants' money until it collapses. Because blockchain transfers are usually final and the recipient may be anonymous, prevention is the only reliable defence, and prevention is mostly a matter of recognising the pattern before you act.
This is the most consequential subject on the site, so it is deliberately concrete. Each term below describes a real mechanism, what it looks like from the outside, and the specific mistake that lets it succeed. The risk terms at the end cover the failures that are nobody's fault in particular, such as a smart contract bug or a change in regulation.

Common questions
What is the single most common way people lose crypto?
Giving away access rather than being hacked. That includes typing a seed phrase into a website, approving a transaction from a link sent by a stranger, and being talked through a "support" process by someone impersonating a company. No legitimate service needs your seed phrase.
Can a crypto transaction be reversed if I am scammed?
Almost never. A confirmed blockchain transaction is final by design, and there is no chargeback process. Reporting the theft is still worth doing, but recovery is rare and anyone who guarantees to recover stolen crypto for an upfront fee is running a second scam.
How can I check a project before putting money into it?
Look at who is accountable, whether the code has been independently audited, how the supply is distributed, and whether the returns being promised are explained by anything other than new deposits. A project that answers none of those questions clearly is telling you something.
