Hello. I'm looking to setup a cold wallet to store my XMR in. But I have a couple questions regarding it.
1: Is it possible to setup a view-only wallet that also has the ability to see outgoing transactions without having my spend key on it? (and if so, how can I set this up using the Monero CLI wallet?)
2: Do view-only wallets still have the ability to setup subaddresses so I can receive xmr from people without giving away its public address? Or must I setup an intermediate hot wallet for this purpose?
3: Can I sign transactions using the offline computer, which will have my private spend key, without it being connected to the internet? (And does doing this compromise the "coldness" of the wallet in any way? Considering this PC is never connected to the internet?)
