The whole whitepaper assumes that everybody always has the gigantic tangle.

I got the information that it should work via clustering. But no single word in the whitepaper about that. In my theory I cannot validate a tx if I do not have the whole tangle. I cannot know if he has the funds or not. Now I can trust a cluster or simply validate without knowing if tx is valid. Tursting a cluster would be centralized.

Marketing and website of the company is pretty good. But they actually never try to explain how it really works.

In my opinion people will never use this system because it is way to abstract and nobody understands it (i it is really a valid system and no scam).

Try to ask in their slack for information. They will spam you with pointless articles (about swarm intellegence, human stampedes, human crush, whatever) and not even try to explain it. This seems pretty scammy. Many cryptoscams are easily spotted, this one would be unspottable, because they can just claim you do not understand it.

Information from slack:

"It's a whitepaper on tangle, not on iota swarms".

That was ther reasoning why no single sentence about how it actually works in the whitepaper. So in reality they did not even reveal how it works in their whitepaper. This iota swarms whitepaper will come next year.
