I asked this in the Telegram channel but no one responded.
I understand that Nexus, as a quantum-resistant blockchain, is more advanced than the technology used in current hardware wallets. But what makes hardware wallets so secure is that it is impossible to extract the private key from them. From what I can see with Nexus, you have a wallet backup file stored hot on your hard drive, and a password. A bit like using a keystore file based hot wallet with other blockchains.
So all someone would need to steal my funds is access to my wallet file and my password? And if my laptop has a virus or some kind of spyware/malware it would be possible to get these 2 things. I must be missing something!
