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?
Yes, sounds like a contradiction but in their whitepaper they actually don't call the 3k ETH soft cap but 'goal'. I guess they aim to collect at least 3k eth but are still able to develop their platform in case they don't reach this goal. Maybe dev can clarify this?
I think 3k ETH should be enough for them. With this amount should allow them to develop a nice platform without any financial problems.
