Blockchain Germany by

If you are interested in German Blockchain startups, you can find our audio-only podcast “Blockchain Germany by” here:


As opposed to the usual Youtuber or Podcaster in the Blockchain space you don’t pay thousands of Euros to be here. AND neither am I invested in you guys. I am also getting NO kickback.

For everyone who is surprised about that, many channels work like this. Just pay attention to the people in Telegram Chats who ask for admin emails and “business proposals” they usually sent an offer with a price tag of several thousands of Euros, sometimes upwards of 50.000 Euros, just to be on their channel. Oh, and before I forget: They usually only want cash, they don’t take crypto.

Make sure you vet your main blockchain information source before you fall into those traps.
