I am a public speaker and trainer about Bitcoin and “blockchain” technology.

I have been active in the field since 2013 as organiser, speaker and entrepeneur.

I have a distinct vision about blockchain technology that is grounded in realism and honesty. I write articles, engage in debates and am always open to speak about the topic.

I believe in building: I have (co-) founded the Nxt Foundation, Jelurida B.V. and Blockchain Workspace.

These days, I mainly am a public speaker and teacher. I design and implement trainings and teaching programs.

I deal with the fundamentals of the industry:

  • What is Bitcoin and how does it work?
  • Why is Bitcoin special and what could make blockchain tech special and useful to the world?
  • How can you use Bitcoin and blockchains and which use cases make sense at the moment?

You can book me for speaking engagements, training or debates via the contact form.
