hi everyone just thought I would do a post for Newbies as I am myself when you use your ledger Nano s with bit coin wallet and it generates a new receive address every time this is nothing to be worried about it is a safety feature you can same address over and over again but ledger Nano s recommends use different address
https://support.ledgerwallet.com/hc/en-us/articles/115005470065-Transactions-and-addresses-issues
and check out point (6)
Please note that your Ledger wallet generates a new address each time you want to receive a payment, thanks to the Hierarchical Deterministic (HD) support. Each address generated by your wallet is yours forever, you can use them several times or just once at your convenience, it won't cause problems - even if it may be safer to use each address only once.
hope you find this useful regards cryptotipp
