1. Lacking of blockchain advantages
This is a subjective topic but the only feature that appears to be really advantageous are the lower transaction fees. There are many other ways to solve this without having to use blockchain technology.
A consistent, value added, raw data stream could be a gold mine that keeps on giving. Databroker DAO attempts to multiply our connectivity to worldwide sensor data by creating a marketplace for all sensors that utilize the Internet of Things (IOT) concept. Business is expected to be conducted in several sectors that include commercial, private, and government. Even with a monopoly on data, profit can suffer as there are inherent problems with only providing raw data. Each data stream would be of more worth if workflow specific functionality was developed to aid in sensor interpretation to a user that acquires the data. Functionality such as chart options, templates, exports, and further customization need to be thoroughly considered. From an investment perspective it's hard to forecast, the project will require enough demand to bring up its token price and right now the demand isn't looking very high.
