I just watched Bidium's official video on YouTube and it somehow boggled me whether Bidium is an exchange or an auction or a sort of Hiring center ala LinkedIn? I mean, why facilitate 3 different industries under one platform? I'm a bit lost, really.
I think you need to read the whitepaper of Bidium in order for your confusion to be cleared. Bidium is a bidding marketplace for hiring freelance. It is bidding in a sense that the freelancer will sell their product and services through an auction. Simple platform but it really helps a lot for the clients to find a better work and outcomes that they want to be.
I read their white paper and they will be launching an exchange platform and an exchange app, then a freelance platform and a freelance app, then an e-bid marketplace and an e-bid market app. They are to launch three platforms based on the roadmap.
