Why there is a very big gap between the soft cap and the hard cap?
Soft cap 5,000 ETH
Hard cap 153,000 ETH
More than 30x.
the soft cap needed to be reached in order to develop and advertise the coin a little more leading up to the ICO. The hard cap doesn't need to be reached, they're just aiming for that amount as a best case scenario.
From that 153,000 ETH hard cap, i think it means this project has a very big potential and so many developments they have planned to do with more and more raised amount.
