NO NO NO!!!
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.
So you admit only 100Gh/s of power mining, but if i remeber well, unfortunately i have no screenshot, before they disappear the hall of fame on the site about the top owners in mining power, owned very much more than 100Gh/s, so as you want to defend, there is always some liars in admins words.....
No I think that is the actual mining being done is around 160 GHs. Users own 500 GHs of scrypt.cc mining. However I think it takes 5 GHs of scrypt.cc mining make 1 GHs of real scrypt mining. I think this is a pretty common problem with a lot of cloud mining sites to various degrees.
Scrypt.cc Admin has clearly stated many times that he will no longer provide any proof of mining. So there is only indirect evidence.
EDIT: This is fun but I have to sleep. Back tomorrow ...
