Techub News: Privacy email system Dmail Network announces that all services will be gradually discontinued starting May 15. Dmail Network stated that the main reasons include the high costs of decentralized infrastructure (bandwidth, storage, computing), making sustainable operation difficult; failure to find an effective payment model or commercialization pathway; tokens lacking clear large-scale use cases and a closed-loop economic model; underestimation of the cooling trend in the crypto market; and the departure of core team members leading to insufficient operational capabilities.
