Bidium can't achieve the hardcap in just a couple of weeks. Just imagine, the gap of their token sale is just for 5-6 weeks. I don't know what they are thinking but to be honest, bidium has a potential to be failed. The period is too short compared to other project who had more than 11 weeks.
If they can't reach the softcap, there is a possibility that they will extend their ICO. In my opinion, the team knows it already. They will not indicate a specific period if they know that it is delicate. Probably, the team already estimated that 5-6 weeks is enough because their project will be sold out fastly.
