I think some people are too lenient on those issues, it's not like they tried to build a rocket and this failed at launch, they, well, they did nothing! They issued a token (2 minutes), and they put up a mock-up of a shop website without even filling in basic parts, another 5 minutes. If I plan on taking payment from you with the promise of building you a house while I know nothing about that, I don't have any studies, any machinery, or anything but the first thing is to pay my friends and relatives out of that money is a scam from the start!
I do have the impression they tried, but they have no idea how to do it. They outsorced the website to a company called Accubits. This company took months to do what you can now find on icechain.org (a wordpress page?). I did write to Accubits and they confirmed that they worked for them. At some point icechain stopped working with them "due to dissagreements" and restarted with a company called Suffescom. They did what you see on icechain.ch. The founders themselves can not even do such a simple site by themselves.
Getting information from them in the Telegram group was next to impossible. I stayed polite, didn't even start to ask real critical questions and got banned two times without notice. While 400 members in the group were mostly silent. No one asked any real questions. Basically only people they personally know where active and only shilling the 'project'. I concluded that most Telegram members are fake (bought).
That also made me question their private sale: They said 19,181,982 tokens were sold at 0.04$ per token. That's 767,279$. I think that's wildly exaggerated - it's probably a fraction of that. They are lying so often. You can't trust a word they are saying.
On the last whitepaper the CTO is called Glen Huang

No sign of any icechain mentioned anywhere, same for other team members that I got a hit on the images, so are you sure those people even know they are involved in this?
It's reassuring to see that you came to the same conclusion here. As I staded in my second post mentioning this paper in this thread:
I tried to contact these people. I found the email address of one of them and wrote to her. Never got an answer though.
