One of the interesting speakers at The Blockchain Day in Hamburg, where I was participating in a blockchain panel, was Frederike Ernst, COO of Gnosis: a prediction market on the blockchain. Gnosis raised $12.5 million by doing an ICO on the Ethereum blockchain. How do you start an ICO? Gnosis seems like a good and legit product but does she think her product is over valued because of the current popularity of the ICO market? Frederike shares her experiences!
