Frequently asked questions
What's the single most important security habit?
Never entering your seed phrase anywhere digital — and never sharing it with anyone, ever. After that: hardware wallet for meaningful holdings, and quarterly approval hygiene.
I got scammed — can I get my crypto back?
Blockchain transactions can't be reversed, and anyone claiming they can 'recover' your funds for a fee is running a second scam. Report to the exchange, authorities and Chainabuse, and secure what remains.
