How Hacks Happen

Most Bitcoin thefts do not break Bitcoin itself. They trick people. Fake websites and fake wallet apps ask you to type in your seed phrase. A seed phrase saved as a photo, a note, or in cloud storage can be stolen if that account is ever broken into. Malware on a computer can read your files, or quietly swap a copied address for the attacker's address. Fake support agents message you and ask for your seed phrase. Real support never needs it.

Other Weak Spots

A hardware wallet bought from an unknown reseller may have been tampered with before it reached you. With a SIM swap, an attacker takes over your phone number and catches text message codes for your accounts. Weak or reused passwords let attackers into exchange accounts and email. Approving a transaction without reading it can send coins to the wrong place.

Stay Safe

Write your seed phrase on paper or metal, and keep it offline. Never type it into a website. Buy hardware wallets directly from the maker, and check that the packaging is intact. Check the receiving address on the device screen before you confirm. Use an authenticator app instead of text messages for two factor login. This video is not investment advice.
