Yes, there is such a trend. On the private sale is understandable. But why do they hide the results of public sales?
I also do not understand what it is connected with. It seems to me that the result of public sales is positive, the team did a good job.
Hiding data on the results of the ICO means that sales are going badly, although the project is promising. And look at their website, they changed the end date of the ICO - December 26th.
Hiding data doesn't mean anything. Just in addition to the sale of tokens, there are many aspects, legal, technical, partnerships and others. And extend the term of ICO for the odds to settle all issues.
The aspects that you are talking about and the extension of time for collecting funds are different problems and together they are not connected in any way.
