2nd December 2021, 18:00 - 21:30

Buy tickets

Switzerland has been one of the leading players in the global adoption of tokenized digital assets and Distributed Ledger Technology (DLT). With people being able to use cryptocurrency to pay anything from a restaurant visit to their taxes the possibilities seem endless. But with all the opportunities that these digital currency alternatives seem to present, we ask ourselves – how sustainable are cryptocurrencies?

Elon Musk turned this question into a hot topic when Tesla suspended Bitcoin saying: “We are concerned about rapidly increasing use of fossil fuels for Bitcoin mining and transactions, especially coal, which has the worst emissions of any fuel. Cryptocurrency is a good idea on many levels and we believe it has a promising future, but this cannot come at great cost to the environment.”

Come to this event to discover and discuss:

  • The amount of energy being consumed by cryptocurrencies
  • Why some cryptocurrencies are more energy efficient than others
  • The volatility of cryptocurrencies
  • If cryptocurrency can be a lever for a more fair society
  • The ethics of cryptography

Join us for this event to learn about opportunities and challenges that come with cryptocurrencies!
