Impressed by the team members. WP is very long, need time to study it properly.
You may look at their website and some video on youtube so you have bird's eye view of their project. As far as I can grasp is that they offer very minimal amount of fees for trading and some have no fees for biding, hiring. The price of their ICO is very affordable. you may invest ASAP while the token is low once that it go to exchange it will surely rise because they have a good project and reputation because of their team members.
I suggest you to watch videos in youtube to have a more knowledge about the bidium, because if you stick only in reading the whitepaper it will difficult for you to understand what bidium is.
In additonal, bidium is a decentralized auction or bidding marketplace and also offers to a job that wants to be a freelancers.
