One of the benefits of this project to the sellers is they will get a 50% Ad profit share, which is good because even though you can't sold or all of your product are sold you will still receiving your benefits, and also the buyers will also benefits another 30% of Ad profit share if the product is being sold.
That's what I liked in bidium because both the seller and the buyer would have the right to get benefit a large percentage is given or shared by bidium to sellers even if they can not sell all of their products they will receive their benefits without limitation. Also the buyer the more you can buy the better you will get more percentage or profit. Hopefully the project launched by bidium will be successful.
