📖 I'VE SPENT 5 YEARS LEARNING HOW TO HOLD BITCOIN.
NOW I'M PUTTING EVERYTHING INTO ONE BOOK.
Buying bitcoin takes 2 minutes.
Holding it safely for the next 20 years is a whole different game.
I've seen it up close:
- seed phrases saved in screenshots
- "secure" setups with a single point of failure
- families with no idea how to recover the coins
- people losing everything to one phishing email
Who's writing this?
🔐 5+ years mastering self-custody
🤝 10+ clients guided 1:1 every year to secure their bitcoin
🛡 Currently writing a complete OpSec & digital hygiene guide
🎬 Working on a mini documentary on the well known "Satoshi Nakamoto"
All that experience is going into "Bitcoin Hodler : The Ultimate Guide to On-Chain Sovereignity"
📚 37 chapters
✍ ~60,000 words
📄 Nearly 400 pages
Not a get-rich-quick book.
A manual for people who plan to still own their bitcoin in 2040.

HTTPS & VPN: A Closer Look
In 2026, browsing the internet without protection is like sending an open postcard:
"Anyone on the network can read your data in transit."
HTTPS and VPNs are the essential duo for encrypting your connections and masking your activity, here’s why, and how to use them effectively:
1️⃣ HTTPS: the baseline encrypted connection (the padlock in the URL bar).
HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP. It uses TLS encryption to protect the data exchanged between your browser and the website.
Why does it matter? It prevents interception (man-in-the-middle attacks) on unsecured networks: passwords, card numbers, messages… everything stays unreadable to an attacker.
In 2026, HTTPS adoption is massive: according to Google’s Transparency Report, 95–99% of Chrome traffic worldwide goes over HTTPS (up to 99% on Android and ChromeOS).
Browsers like Chrome, Firefox and Safari are becoming ruthless: they block or prominently warn against plain HTTP sites, especially since recent updates.
Google penalizes HTTP sites in search results, and users see “Not Secure” warnings that drive them away.
HTTPS best practices:
-Always check for the padlock in the address bar before entering sensitive information (banking, email, shopping).
-Turn on “HTTPS-Only Mode” or “Always use secure connections” in your browser settings (Chrome, Firefox, Edge).
-Use extensions like HTTPS Everywhere (or the built-in equivalent) to force HTTPS whenever it’s available.
For personal or business sites: switch to HTTPS with a free certificate from Let’s Encrypt (automated and renewed every 3 months).
2️⃣ VPN: your encrypted, anonymizing tunnel
A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a remote server.
Your traffic exits through that server, hiding your real IP address.
Why and when to use one?
On public Wi-Fi (cafés, train stations, airports, hotels): protection against local snooping (sniffing).
Against tracking by your ISP (internet service provider), governments, or websites that track your IP.
Getting around geo-restrictions (streaming, blocked sites).
Partial anonymity: your real IP is hidden.
Advantages in 2026:
Modern protocols like WireGuard (fast, lightweight, highly secure) dominate; OpenVPN remains the most battle-tested.
Advanced features: kill switch (cuts your internet if the VPN drops), split tunneling, multi-hop (double hop), ad/tracker blocking.
Watch out for these traps:
Avoid free VPNs: many sell your data, inject ads, leak, or run compromised servers.
Choose audited no-logs services (a no-logs policy verified by independent third parties).
In 2026, the top privacy-focused picks are still:
@mullvadnet: ultra-anonymous (account by random number, cash/crypto payment possible, regular audits, open source).
@ProtonVPN: an excellent balance (annually audited no-logs, open source, generous free plan, Secure Core for hardened routing).
@ivpnnet: similar to Mullvad, privacy-focused, transparent audits.
All three are regularly ranked among the best for privacy by WIRED, PCMag, Tom’s Guide, Wirecutter and privacy experts (2025–2026 reviews).
VPN best practices:
-Turn it on before connecting to public Wi-Fi.
-Check for a kill switch and leak protection (DNS/IPv6/WebRTC).
-Use WireGuard for speed and security.
-Test regularly (sources in comment section).
-Combine it with HTTPS: a VPN protects the route, HTTPS protects the content, site by site.
In short: “layered protection”
1. HTTPS = site-by-site encryption (mandatory in 2026).
2. VPN = global encryption + IP masking (essential on untrusted networks).
Neither replaces the other: combine them with 2FA/MFA, a password manager, regular updates, and common sense (no suspicious clicks).
Browsing without these tools exposes your data for no reason, in 2026, this is basic digital hygiene!
Biometrics (fingerprint, facial recognition, iris, voice, etc.) seem ultra-modern and extremely convenient: a simple glance or a finger placed on the sensor, and hop, your phone, computer, or account is unlocked.
But behind this convenience lie serious risks that often make it a bad idea as a primary or sole security factor.
Why biometrics is not the miracle solution, unlike a password or PIN code:
-You can’t change it.
-Your fingerprint, face, or voice is permanent.
If a hacker manages to copy or steal it, you can’t generate a new one the way you would with a compromised password.
It’s a unique key you carry with you forever,
It is vulnerable to spoofing (usurpation).
Attacks are multiplying with AI and deepfakes.
Recent examples (2024–2025):
1.Malware such as GoldPickaxe (linked to Chinese groups) steals facial data through compromised apps to create deepfakes and empty bank accounts.
2.Fraud rings in India have manipulated systems like Aadhaar using spoofed fingerprints (printed or synthetic) to access government benefits and financial services.
3.Deepfake injection tools on jailbroken iPhones trick banking apps that rely on facial recognition.
Even systems with liveness detection are sometimes bypassed by advanced AI videos or 3D masks.
Biometric data can be stolen.
It is stored (often as mathematical templates) on your device or with the manufacturer, in the event of a breach at Apple, Google, Samsung, or a third party, these templates can leak.
Worse: once stolen, they remain usable for life, unlike a password that you can immediately replace.
No revocability.
If your password is compromised (phishing, database leak), you create a new one in two minutes.
With compromised biometrics, you lose that option.
That’s why experts insist: never use biometrics alone, and prefer revocable methods.
