Most people are using Bitcoin without truly understanding it

Your coins show up. Your hardware wallet works. Everything looks secure. But you can't explain how it actually works. You don't know what you'd do if something went wrong.

A lost device. A corrupted backup. An unexpected error. That's when the panic starts. You don't know if your Bitcoin is gone forever or if there's a simple fix. Without understanding, every decision feels like a gamble.

Bitcoin doesn't forgive guessing

You can't call customer support. You can't reverse a transaction. You can't recover funds from a setup you've lost the keys to. Real security isn't about following tutorials — it's about understanding the system well enough to recover, troubleshoot, and act correctly when it matters.

That's why we built The Bitcoin Course.

The Bitcoin Course gives you the foundational knowledge and the hands-on skills to secure your Bitcoin with confidence.

  • ✓Hands-on exercises to build real skills and knowledge
  • ✓Understand keys, seeds, and addresses at a deep level
  • ✓Deep dive into Bitcoin wallets to learn beyond the basics
  • ✓Learn security models so you can design the right setup for your situation
  • ✓Set up Coldcard and Sparrow Wallet correctly

The Four Phases to Master Self-Custody

Setting up your first Bitcoin wallet

Phase 1 — Foundations

Learn by doing.

Set up your first wallet and make real transactions. Understand seed phrases, keys, and addresses through hands-on experience — not just theory. This is the foundation everything else builds on.

Complex Bitcoin wallet architecture

Phase 2 — Deep Dive

Understand how it actually works.

Go under the hood. Learn how nodes work with wallets, how seed words are generated, what derivation paths are, and how fees and the mempool work. This is the knowledge layer that makes everything else click — the technical layer most courses skip entirely.

Bitcoin wallet security structures and models

Phase 3 — Security Models

Design your wallet structure.

Compare single-signature, passphrase-protected, and multisignature setups. Evaluate your own risk profile and choose the right security model for your wealth — don't just copy someone else's.

Designing a Coldcard Bitcoin wallet setup

Phase 4 — Build

Build your secure setup.

Follow professional-grade Coldcard and Sparrow Wallet tutorials to build the exact same setup used to secure millions of dollars in Bitcoin. Every step verified. Every backup tested.

Cole presenting at Adopting Bitcoin conference

Thousands of hours securing Bitcoin, so you don't have to.

I'm Cole. You might know me from the Southern Bitcoiner YouTube channel, where hundreds of thousands of people have learned practical Bitcoin security.

I've helped clients across the globe secure millions in self-custody, presented at conferences like Adopting Bitcoin, and been featured on podcasts like Robin Seyr and Mantas Jaskys. After 4 years helping others, I've seen exactly where people get stuck, what they misunderstand, and what makes the difference between a setup you can trust and one you can't.

This course is everything I know about securing Bitcoin, distilled into a clear path you can follow — built on the same setups I use to secure my own Bitcoin.

Questions

Frequently asked questions.

No experience required. The course teaches Bitcoin security from the ground up — we start with the fundamentals (how wallets and keys actually work) before moving into the tutorials where you build your own secure setup. Complete beginners can follow along step by step.

No. The course includes a shopping list with everything you need, and the first sections cover fundamentals that don't require hardware. Most students buy their Coldcard and any accessories after they understand what they're buying and why.

The video content runs about 8 hours across 34 lessons. Most students work through it over 1–3 weeks depending on how much setup work they do alongside it. You have lifetime access, so there's no rush.

Yes, most of the information is out there if you're willing to piece it together from dozens of videos, some of which contradict each other or are out of date. The course gives you one structured path from zero to a setup you can trust — taught by someone who secures Bitcoin for a living. You save time, avoid outdated advice, and don't miss the steps that actually matter.

No. The course focuses on Coldcard and Sparrow Wallet — the tools I actually use and trust to secure my own Bitcoin. I don't teach setups I wouldn't use myself.

Most people with a hardware wallet can use it but can't fully explain how it works — and wouldn't be confident recovering from a failure. The Fundamentals and Security Models sections alone are worth it if you want to truly understand your setup, not just operate it.

The course teaches you to build and understand a secure setup on your own, at your own pace. Consulting is 1-on-1 live calls where I build the setup with you over screen share. The course is for people who want to learn and do it themselves. Consulting is for people who want me to walk them through it personally. Many consulting clients take the course first.

I recommend completing the Fundamentals section even if you've used Bitcoin wallets before. After that, you can jump to whichever setup tutorial matches your goals. The fundamentals give you the foundation that makes everything else easier and safer.

The course is self-paced and doesn't include ongoing 1-on-1 support. The $547 tier includes a 1-hour private call where I review your setup and answer your specific questions. For hands-on, personalized guidance beyond that, see my consulting services.

Card payments are processed through Teachable. If you'd prefer to pay in Bitcoin (on-chain or Lightning), use the Bitcoin payment page and I'll set up manual enrollment.
