so am i, or am i not, obscuring a BTC transaction's IP address when running a wallet from a VM?
When you spend bitcoins in your setup, via what path do those transactions make it to the rest of the network? i'm sending them thru the VM's network adapter (NAT) to the host, then via wifi to a router, to modem, to net. |

That wouldn't obscure the IP as the transaction is still being relayed by your connection. If you had a VPN set up on the host and shared the VPN's TAP adapter to the VM, that would obscure your IP.

In that case running in a VM isn't doing anything at all in terms of obscuring your "real" IP address. If you want to submit transactions anonymously, you need to make sure your node can only communicate with the network via Tor or I2P. A VM can possibly help you there, because you can set the appropriate firewall rules at the host level which restrict the ability of the guest machine to communicate outside a limited set of endpoints. So you could run a Tor node in one VM and a Bitcoin-Qt node in another, configure Bitcoin-Qt to use Tor, then use firewalling tools on the host to block all packets coming out of the Bitcoin VM except communication to and from the SOCKS listen port on the Tor VM. Then you're safe as long as your Tor node, or your host OS, isn't compromised. But again, getting everything right is a bit like getting surgery right. It's difficult to explain the process via a forum post. |

actually forgot that part. yes, i have a VPN on the host. what is the TAP adapter? |

That's better than not having one, but not as secure as routing through an anonymization network. |

Assuming you're using NAT on the VM to the host, and your VPN is connected then your IP will already be that of the VPN. Then there's leakage though, if you're using OpenVPN or similar you can specify routing of DNS over the VPN and for a ''kill switch" if the VPN disconnects. Also, not sure if it still applies, but bitcoin-qt used to use IRC to get a list of peers... not sure if this is still the case but it can be disabled in the config. (of course, this will also be routed over the VPN, but it's something to think about if you decide to connect bitcoin-qt via TOR instead) Installing TOR on the VM or Host and setting bitcoin-qt to use it as a proxy (and disabling IRC) is still safer, as ranvier says... |

let me ask your opinion and that of the other tech experts here on something runeks said over in Reddit.
that by putting one's wallet inside a VM, it becomes much more secure, if not impossible for a gubmint entering your pc via the VM to get out of it and access your IP address thru the native OS and connected router. is this accurate? and does it depend on whether one's network adapter uses NAT or bridged?
secure against what? discovering your IP? certainly not. The bitcoind (or whatever network-connection-using software) within the VM accesses the network via your router, just like any other device behind the router (except maybe using an additional hop depending on config). You don't need to break into the VM to find the IP address, just look at the traffic. |

definitely not. You would use an anonymous VPS, a VPN, tor, i2p or some trustworthy proxy for that. |

only 3 days in BTC history where the price has closed higher. On which exchange? Mt Gox closed at $162.30, 187.50, $230, and $165 April 7-10 respectively. It also reached intraday highs of $166.42 and $162 on April 24th and 25th. |
