Digital economy through the lens of research.

Juraj Fabuš

I study how Bitcoin, AI and digital transformation are reshaping markets, education and business. I then work with universities and public administration to turn that research into working services, more practical teaching and decisions you can defend.

What I work on

Bitcoin and investing

How a fringe experiment became part of the financial system — and what that means for an ordinary person weighing up whether and how to invest.

AI and higher education

Artificial intelligence did not reach universities through strategies and directives, but through students and their laptops. I study what that actually does to teaching.

E-commerce and digital transformation

Digital transformation is not new software. It is a change in how a company earns, communicates and decides — software is only the consequence.

Selected research

Publications worth reading — explained so they make sense outside academia too.

What the halving does to Bitcoin's price

It shows how Bitcoin can be approached with data instead of opinions — and where that approach runs into its limits.

How the world taxes cryptocurrencies

If you have ever wondered how profit from cryptocurrency is actually taxed, this review shows why there is no simple answer anywhere in the world.

What shakes Bitcoin's price

Instead of another price story it offers a sorting device — which layer of Bitcoin actually shook at which event: the market, trust, the protocol or the institutions.

Investing5 min read

Trusting is fine. Blind faith is not.

You do not have to be an analyst to invest. But you should know what you are getting into, where your return is supposed to come from, and what would have to happen for it not to arrive.

Teaching

I teach at the Department of Communications of the University of Žilina, in the Electronic Commerce and Management study programme.

Current

Web Design and Development

A course for students of electronic commerce, not for programmers. Over one semester a student designs their own project, then builds the site from that design with the help of AI, deploys it and presents it.

Electronic Commerce

How commerce works on the internet — from business models and logistics through security and electronic payments to marketing. In the lab classes every student builds their own online shop and defends it as a semester project.

The Information and Communication Technology Market

How the ICT market is structured and where it is heading — market structure, IT services from outsourcing to cloud, the legal and economic framework, and the question of when money put into a company's information systems actually pays off.

Currently working on

  1. A textbook on Bitcoin and digital assets in e-commerce

    Together with co-authors I am preparing a university textbook (working title, roughly 200 pages) for e-commerce students. I am writing the chapters on cryptocurrencies as a payment system in online shops and on financial management and investing in digital assets.

  2. Guest Editor of the Special Issue “Cryptocurrency and Digital Cash”

    I am editing a special issue of the FinTech journal (MDPI) on cryptocurrencies and digital cash. The submission deadline is 30 November 2026.

  3. A chapter on digitalisation and the urban circular economy

    For a textbook on the circular economy in cities I am writing the chapter on how digitalisation changes the way it works. It does not create it on its own, but it lowers information and coordination barriers. The text is with the editor and the book is being compiled.

About me

I research the digital economy, teach it, and work on IT projects that have to hold up outside of theory.

Alongside academic work I help run public-sector IT projects — how they are designed, tested, deployed and explained to the people who use them every day.
