50 BTC worth.
EDIT: Here's what I don't understand... How does he know it was his former employee?
I lost a bit more than 560,000 DGC due to an ex-employee copying the wallet file and later key logging the password from the work computer. Most if not all of it was already dumped (those are the massive sells you noticed yesterday).
This will not affect anything when it comes to DGC's development. I'm probably more motivated if anything.
How does he know said ex-employee made a copy of the wallet file, and keylogged the password? How does he know it wasn't someone outside who managed to hack his network or something?
Reason #54 why the whole story is utter BS.
