i stressed on everything must be able to work offline that in case even if i am already hacked, i am not in danger of losing anything except the coins i want to spend which will always be on the machine whatever it's online or offline.
What machine are you referring to? The host? As I wrote earlier, if your host gets hacked then your VMs should be also considered as compromised. Ideally, it would be great if you used a completely separate machine to sign your transactions. Creating raw transactions using Bitcoin Core is a bit complicated so I would recommend you either using Armory + Bitcoin Core or Electrum (wallet backup would be in a form of 12 words which you wouldn't need to update after each transaction unlike your current setup).
correct me if I am wrong please
lets suppose my (host) pc is (currently) hacked
if I went
(totally offline) and did the following
- created few wallets in my vm
- backed them up using different mediums
- copied my old wallet into my up-to-date bitcoin core and sent the coins to that few wallets i created
- done
what the risks i am facing me and/or what could go wrong ?
the only thing I will risk in the few satoshis I would have on my machine which I will be spending as I mentioned earlier I will leave some satoshis on my machine as I need to sell them
