Delphi Labs COO Kevin Simback has raised concerns over the $200 million valuation of privacy chain project Octra, which is preparing for a public token sale. Simback highlighted that the valuation has surged fivefold since its $4 million seed round, questioning the demand for the project. In defense, Octra co-founder Alex explained that the initial lower valuation was due to the project being in its conceptual phase. He asserted that the current valuation reflects significant progress, including sandbox testing, comprehensive documentation, and a stable network. Octra's public token sale is scheduled for December 18 on Sonar, targeting $20 million for 10% of the OCT token supply.
