If you are an activist, journalist or any person susceptible to be persecuted by a three-letter agency, remember:

- Use public wifis (libraries, coffee shops, etc).

- Don't pay with credit card to the places you go, use cash.

- Always use Tor or i2p.

- Use a freshly installed operating system so that there is no fingerprint, Qubes OS and Tails help you in this.

- Be careful with cameras, both outdoor and indoor, for example bank ATMs, inspect the area before.

- Never use your personal email accounts, etc, all accounts you create should use pseudonyms and be created under Tor, in case you can not create them in Tor with a reliable vpn, ultimately from a public wifi.

- Do not always go to the same location, change city.

- If you must make payments use Bitcoin, especially Lightning.

- If you must receive payments, use Bitcoin and then coinjoin.
