WARNING! WARNING !
Just had 1 BTC stolen. Deposited to invest, but the balance was transferred out before I even had chance to invest. Since it looks like I'm not the only one in the last few days - I would consider the site compromised for now, at least for deposits.
Will contact SD - but I guess there is not much they can do. Hope this post saves someone else
I know this might be common sense but are you sure you've sent it to the correct deposit address. Or maybe you have some type of virus on your computer, very weird for this too happen.
