The Golden Rule
Assume any public conversation about crypto attracts scammers. Anyone who DMs you first with “help” or “an opportunity” is likely a scammer. Never share your holdings, seed phrase, or wallet addresses publicly. Use end-to-end encrypted channels for sensitive discussions. If someone contacts you claiming to be support, verify on official channels before responding.
Bottom Line
Public crypto discussions attract scammers. Use Signal or ProtonMail for sensitive conversations. Never share holdings, seed phrases, or wallet addresses publicly. Block and report unsolicited DMs about crypto. Verify any support contact on official channels. Assume anyone who DMs you first in a crypto context is a scammer until proven otherwise.
