I just now looked backed into my wallet and I notice that the address is different. It does mention my same balance though. How is this possible ?
The ledger nano s is a Hierarchical deterministic (HD) wallet. This means it uses your 24 word seed (which you hopefully backed up correctly at the initialisation)
to create addresses out of it. You can think of it as a mathematical equation where your seed is modified with a 'counter' to generate an
infinite amount of
public-/private key pairs (an address is the represantation of the public key).
This is not necessary security-wise but recommended for privacy reasons since the blockchain is accessable by everyone.
