Hello,
is there some form of tutorial for using Bitcoins with Qubes,
considering that I have no experience of bitcoins?
It seem I should have a VM for a hot wallet for making transactions
and another for a cold wallet to keep the bitcoins. But have no idea
if it is possible to move bitcoins between the two
Also imagine a good practice would be to make a backup of the VMs
containing the wallets using Qubes backup.
It would be also interesting to know which clients you consider safer
for buying and selling bitcoins.
Thanks

Hi, Fran. I've done exactly this using the Electrum bitcoin wallet. I
have a dedicated hot ("watching") wallet in its own VM, and a cold
(offline) wallet in a separate VM that's never network-connected.
Although I'm hardly a bitcoin expert, I don't think it's a matter of
"transferring bitcoin from one wallet to another." Rather, I think the
cold wallet just holds the private keys used when authorizing bitcoin
transactions. For example, if I'm buying something with 1 bc, I generate
a pending transaction in the hot wallet, sign that transaction in the
cold wallet, transfer the signed transaction back to the hot wallet, and
then broadcast it from there. That way, only that 1 bc is ever
vulnerable in a network-connected VM.
If I'm misunderstanding this, or doing it wrong, I'd love to be educated
by a bitcoin guru!
