2 questions about wallets

Hi!
  • What watch-only bitcoin wallets for cell phones do you recommend? (preferably open-source) I'm only aware of Blue wallet but I'd like to hear about any other options you know of.
  • I've been reading about creating a cold wallet with Tails Os and Electrum. If I create a virtual machine with linux and then create a wallet with electrum or blockstream wallet, store the seed, public key and address externally, log out and delete the virtual machine, won't that have the same effect? Do you think it will be less secure?
Thanks

  • You can use Blockstream Green, Electrum, Nunchuk.
  • Electrum + Tails is fine IF you know what you are doing. Messing around with VMs is risky, because even if you run Tails on a VM, certain attack vectors from the host machine still exist. To be honest, if you have normal user needs, you should probably stick to a simple Hardware Wallet. It will be simpler and as good as anything you roll yourself (again, unless you have weird needs or you REALLY know what you are doing).

  1. Blue wallet is fine.
  2. No. Don't do the virtual machine thing. You need to use an offline machine. Even if the virtual machine has no network, you could have a virus in your host machine that is capturing screenshots of everything. Low probability, but I wouldn't risk it.

Tails keeps all data in memory, never is anything written to disk (or the bootable usb) so all trace of your activity is erased when you shutdown the machine.
When you use a VM of linux, you are writing data to disk that will be erased when you delete the VM. You could run a VM of Tails, but the host machine could be compromised.
Get a cheap $100 laptop to boot tails with. Bonus if it has a removable bluetooth and wifi module
