Should I tell people I own Bitcoin?
Quick Answer
The security consensus is clear: don't advertise it. Bitcoin is a bearer asset — knowledge of who holds it is targeting information for scammers, phishers, and in the worst cases physical criminals.
TL;DR
Discuss Bitcoin freely; disclose your holdings to almost no one. Quiet ownership is a core security practice, not paranoia.

Full Explanation
Bitcoin differs from a brokerage account in one brutal way: it's a bearer asset. There's no fraud department to reverse a transfer made under pressure, no daily withdrawal limit a thief must wait through. That property is what makes self-custody powerful — and what makes the knowledge of who holds Bitcoin valuable to attackers.
The threat ladder runs from common to rare. Common: scammers and phishers prioritize known holders — mention coins publicly and the targeted DMs, fake support contacts, and SIM-swap attempts follow. Documented but rarer: physical coercion, grimly nicknamed the '$5 wrench attack,' has occurred enough times worldwide that security researchers maintain a public list of cases. Victims are overwhelmingly people whose holdings were publicly known — from social media bragging, conference talks, or news coverage.
The practical policy most experienced holders converge on: talk about Bitcoin the technology as much as you like; keep your position size to yourself. Don't post gains screenshots, don't reveal holdings at parties, and be vague even when the market is exciting. One exception matters: someone you deeply trust should know your coins exist and how to access your recovery instructions — otherwise your Bitcoin dies with you.
