Well, honestly.. the lockbox thing is just a cheaper version (in terms of functionality) of the nano S.
- It doesn't provide the ability to store all the coins the nano S does.
- It is not supported by ledger live (which has an awesome UI (personal opinion)
- You are forced to use it together with an online wallet (which is an absolute no-go for me)
I would definitely suggest to get the nano S instead of the lockbox-thing.
I don't see any disadvantage compared to the lockbox, only advantages.
You are right, I completely agree with this. Ledger is much better.
However, I believe this hardware Wallet will never let the keys go online. It probably only send the signed transaction to the online wallet.
If the keys are leaving the wallet to the online website there is no reason to have a hardware Wallet.
And blockchain.com is a respectful company..
