3000 eth is a reasonable amount and i can't argue with that for a soft cap.
But the thing is in your website it says:
What is going to happen in case you are not able to collect the estimated funds?
We will continue developing the REPU platform with any collected ICO proceeds, following our tentative roadmap of operational development. We already have a sufficient number of preliminary agreements with supporters involved, which allow us to count on the worthy results of this crowdsale.
So which one is true?
Information of soft cap I found in rating platform:

Imo, if for example they can't reach the softcap, they will refund the investors money. But they will continue the project with another efforts. They already have some supporters and they will work with them.
