Certainly the logs don´t show the complete transaction history... But the final BTC and Khs amounts are kept correctly.

I've been here for several months and so far I wont say it's a scam. I think it is not as profitable as it claims to be, because the mining profits and the Khs price have gone way down since I first invested... But not a scam.

By the way I see that bitcoinera.net is still alive. That site is a real scam, they erased my account robbing my BTC. Not a big amount, but a robbbery anyway.
