This could be legit, but honestly sure looks like a big scam. Huge premine, no miners, no place to sell except for the promise of a scamtopia listing, and they only way of getting coins is the website? Also no way of getting a hold of the dev or any support at all.
Makes me think I need to make an "Idiot test" website. I'll have the same exact interface as this Astrum site but it will say "Send us 1 Bitcoin to find out if you're a idiot."
There is the fund usage table in the first post. As you can see, the most of the funds will be used for listing on exchanges. And there's no need in mining - this is pure PoS coin.
