so people dont know what they are buying? And price was established, how?

With no information available, one way to determine a price would be by the fact that the number of distributed assets is 1/10th that of NXTventure. With NXTVenture trading around 77 NXT, 7.7 NXT seems like the right price for Atomic to me right now.
this calculation is far-fetched...
who says, that the new asset will have just 1/10 of the market cap of NXTventure? It can get a market cap of 1 $ or 1Billion $. Noone knows.
Look at all the things in the coinmarketcap-page and try to choose. Its impossible...
But with 7 its worth 7 million NXT. Hm.. For a pig in a poke?
