This BigVern's story is an utter bullshit.
1. How come he could run BTC, LTC and some unknown shitcoin wallets within the same physical machine AND virtual machine? I don't do this even on my desktop!
2. 13,000 BTC and 300,000 LTC in HOT wallets? BTC was about $580 and LTC $7.5 at the alleged theft time. That's a grand total of nearly $10 million! Again, in hot wallets? Are you fucking kidding me?
3. All wallets on exchange MUST be encrypted with their keys stored elsewhere in top security. Even if a wallet server is compromised, nothing can be sent out without knowledge of these keys. That's a no-brainer.
