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."
