Scrypt.cc Admin claims to have sold 500 GHs of scrypt mining, I don't know any reason to doubt this as it is very consistent with what I and other saw.
So, first you see no reason to doubt, and then you say this:
My claim is the actual mining is probably closer to 160 GHs, of which 100 GHs has been sold to users.
So, what made you change your mind before the end of your post?
lol, you need more focus, then you would see its just a scam plain and simple.
Scrypt.cc sold 500 GHs of mining. (NO DOUBT HERE) However I believe that 500 GHs of CLAIMED mining is really 100 GHs of mining. The 160 GHs is because of the claims that there was an additional 350 GHs not sold to users.
The 100 GHs would be consistent with the awards seen over the last couple of months.
