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.
Setting up your secure channels
Securing your crypto communication is less about installing one magic app and more about choosing the right channel for each kind of conversation and locking down the details that attackers exploit. A few minutes of configuration turns a tool like Telegram or Discord from a phishing playground into something far safer.
Start with the platforms you already use. If you have crypto conversations on Telegram, change your phone number privacy to “Nobody” or “My Contacts” so strangers cannot look you up by number; enable two-factor verification, restrict forwarded messages, and keep your profile photo visible to contacts only. On Discord, restrict DMs from server members, turn off friend requests, and enable 2FA on your account. These small settings close the easiest doors for impersonation and unsolicited contact.
For conversations that actually matter — amounts, transactions, anything financial — move to an end-to-end encrypted app rather than a public forum. Signal is the strongest default: set disappearing messages to one to four weeks so sensitive conversations do not persist, keep sealed sender enabled, turn on registration lock with a PIN, and use an incognito keyboard so your phone does not learn your typing patterns. WhatsApp works well for family, and ProtonMail covers formal written communication. Threema is a good choice when you want to communicate without linking a phone number.
Finally, harden your behaviour around the message itself. Never put your holdings, wallet addresses, or screenshots of accounts into any channel, encrypted or not. If you must mention an address, use a fresh one not tied to your identity, and never paste a seed phrase anywhere — on any platform, in any form. Treat every unsolicited message about an “opportunity” or “help with your funds” as hostile, block and report it, and verify any supposed support contact only through the official website or app you opened yourself. With the right settings and a sceptical default, you can discuss crypto without announcing yourself as a target.
