An interesting article with some tips and tools to enhance your personal ~security and ~privacy.

Here are some of the basics:

Phone/eSim

First option: no-KYC eSIMs — Silent.link (anonymous, paid in bitcoin or Lightning, no name, no registration) or Bitrefill (crypto payments, no account required beyond an email).

@Natalia just wrote about it here #1567252

Email & Aliases

Second: use email that doesn't read you. ProtonMail, or self-hosted mail with GPG where you can. Never Gmail, Outlook, Hotmail. "Free" email is paid for by profiling you, and it sits one subpoena away from handing over the archive.

De-Geolocalize

A VPN doesn't make you anonymous. It moves trust from your ISP (which keeps logs because law) to a provider you chose. So choose one that collects nothing: Mullvad, IVPN, Obscura. The account is a random number. No email, no name. Pay in bitcoin.

Messaging

For one-to-one and small group chat, SimpleX has no phone numbers and no user identifiers at all

For nostr-native group chat, three protocols are worth your attention — we wrote a full comparison of them that goes deeper than this piece can:

For team chat beyond nostr, Matrix on a homeserver you run yourself, or Den Chat.

Own the Machine

Run a sovereign OS on a box in your closet: Start9 (StartOS), Archipelago, YunoHost. One machine runs your services — sync, git, relays, whatever you use.

De-KYC

Bitcoin is pseudonymous, not anonymous. Coins carry history, and an entire industry exists to read it.
Cleaning: Wasabi with a third-party coinjoin coordinator.

You can learn more about Wasabi and ~Coinjoin privacy benefits here #1532071 but also consider that there are plenty of other options to anonymise your sats using ~lightning.

Everyday spending

Large spends: Lightning. Phoenix or Zeus for mobile, or self-host a node if you're moving enough volume to justify it.

Mindset

You don't buy privacy. You operate it, like a garden or a server. It decays without attention.

The goal isn't invisibility — that mirage sells products. The goal is to be expensive. Every wire you pull out raises the price of watching you until, for most adversaries, you're simply not worth it. Perfect opsec is a myth.

Better opsec is the direction, not a destination.
