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.
If you been followning the project from the scratch you will understand how the team is going about their ICO, it is divided into Tiers and you need to be whitelisted to be part of these.
I do agree that the ICO address should be made public for investors to verified what is going on behind the scence
