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.
Based on my understanding in their youtube blog, their main project is the exchange it acts as bidding marketplace to buyers and a freelance platform to employers and their goal is to have a minimal fee to this customers. Should you have read the whitepaper in order to clear things up to you.
