A lot of people underestimate how secure software wallet entropy can be.
A Bitcoin seed does not become secure because it is generated on a hardware device. It becomes secure because the randomness behind it is strong.
Modern Linux systems use a cryptographically secure random number generator (CSPRNG) that collects entropy from multiple system sources and produces unpredictable random data. Wallets like LND rely on this foundation when creating their seeds.
The real security question is not:
“Hardware wallet or software wallet?”
The better question is:
“Was the entropy generation secure, and is the private key protected afterwards?”
A properly generated LND seed has an enormous security margin. The biggest risks are usually not the RNG itself, but operational mistakes:
* exposing the seed
* poor backups
* malware
* compromised devices
Hardware wallets reduce certain attack surfaces, but they are not magical. Their security still depends on trustworthy entropy generation and good implementation.
