About

Measure twice.

I spent years as a finish carpenter before crypto found me. The trade taught me the thing my teaching still runs on: the cost of a mistake is paid by whoever trusted your work.

2016: the rabbit hole

I found bitcoin in 2016 while looking for a way out of the monotony of trading hours for dollars. Price wasn't the hook. The hook was freedom and sovereignty: ownership that doesn't depend on anyone's permission, built on rails no one can quietly bend.

2017–2018: both lives, then all in

Through 2017 I kept the tools and worked crypto around the day job — carpentry by day, blockchain at night. In 2018 I left the trade and went full time. I wrote explainers, dug into new projects, and learned in public; my early pieces on the Gala Games node ecosystem were read by thousands of people trying to understand what "players actually own their stuff" could mean.

The 9 BTC lesson

The education was expensive. I lost 9 bitcoin to security mistakes nobody had warned me about — the exchanges, wallets, and recovery-phrase traps that caught thousands of early adopters. It's the most expensive lesson I've ever paid for, and it changed what I do with my time.

Everything in my training is what I wish someone had explained to me at the start.

Now

Today the work runs on two tracks. BlockFreedom, the company I founded, does blockchain infrastructure and community support for projects. Blockchain Jon is my education brand, where individuals learn the security habits that keep crypto safe: an 18-lesson, plain-language training with no technical background assumed. Not theory — the actual habits, tools, and checks.

Outside crypto, I run a marketing agency. Different rails, same job: building things clients can rely on.
