RE: haha, at a finance fair in Vienna, the room was too small for the BTC-ECHO talk 😂

It's encouraging to see that the finance fair had a diverse range of topics and presentations, including discussions on cryptocurrencies and their potential applications in various industries. The fact that the talk on crypto generated such a high level of interest shows that people are becoming increasingly curious about this emerging technology and its potential benefits. It will be interesting to see how the crypto industry evolves over time and how it can be used to address real-world challenges and opportunities.
