I think the yield seen right now are reflective of the actual amount of mining going on.
What makes you think there is any mining going on? Do you have any evidence for it, or is it purely a guess?
I will add some math for you:
Math with your "mining" rewards:
MH price
0,00078499 BTC
MH reward per day
0,00001344 BTC
If you would run that MH with real hardware by yourself @ LTC network:
MH reward per day with real hardware
0,0001493 BTC
So the reward for real hardware is 91% higher than with scrypt.cc's mh.
That means the ROI for the scrypt.cc admin is 5,25 days if he is running real hardware.
Well, lets say the power costs are 50% of all rewards, then the ROI is 10,51 days
Now tell me, why should the admin not buy the hashrate out of the orderbook?
This is an excellent point, but none of the scam's defenders seem to have even noticed it.
What math, it is just numbers thrown out.
If you look at current Titan sales they are being sold for around $12/MHs. 0.05 BTC which is actually about 64x what MHS at scrypt.cc costs. Granted those prices are high, but that is what people are paying. You can find a few sales threads on forum.gethashing.com.
