The lack of contribution information at official site doesn't look reliably. Why don't you show it? How do we know if you contribute more, for example??? This discourages potential investors.
I think they explained many times about these why they are keeping it as confidential because of security reason and their hard cap is 15 million Dollars. I think they will reveal the details once the ICO is completed.
Guys, the smart contract is open - you are free to check any contribution and current progress of the sale right now.
And this info will be added to the website soon.
