Cách tránh lừa đảo Bitcoin

The hard truth of Bitcoin security is that the cryptography is rarely broken — people are. Almost every loss starts with a scam or manipulation that gets you to hand over access or send coins voluntarily. Learning the common patterns is the single best defense.

The classics recur constantly: 'giveaway' or doubling scams ('send 1 BTC, get 2 back'), fake customer support that messages you after you post a problem, phishing sites and emails that mimic your exchange, fake wallet or exchange apps, and romance or investment schemes ('pig butchering') that build trust over weeks before stealing everything.

A few rules neutralize most of them. Never share your seed phrase or password with anyone — no legitimate service ever needs it. Treat unsolicited messages, 'urgent' warnings, and guaranteed-return offers as scams by default. Reach sites by typing the address or using a saved bookmark, and download apps only from official sources after checking the developer.

When something feels off, slow down — urgency is the scammer's main tool. Verify independently (the official number, the real domain), and never let anyone pressure you into a quick transfer or into installing remote-access or screen-sharing software. If you've already shared credentials, move your funds to a fresh wallet immediately.
