Hi guys
It's that time of the month again to buy some BTC. I realized my ledger suddenly shows new public keys for me to recieve btc to. I did a test and sent myself 40 cents to my old address, and then again to the new one. The incoming and outgoing addresses were still my old public key.

And yes BCASHers, its possible to do that on bitcoin, I even sent one at 1sat/byte.

I know that one private key can generate more than one public key.
My question here is, is it fine to save one of these public keys and use it as a receive address permanently? Will my ledger just create a new receive address each time funds are received that is usable for privacy reasons ?

Only had this thing for a few weeks now, so im new to these kinds of wallets.

P.S. I see unconfirmed transactions are quite low today, I can turn all my inputs into one input by sending my BTC to myself right ?

I notice you are using "public key" expression, but obviously think on BTC address. Your Ledger is creates new BTC address every time you use previous, as others say it is for security/privacy reason. Public key can not generate new public key, all your addresses and private keys are generated from that 24 word seed which was generated when you set up your device. This is most important thing you need pay attention and keep it in safe place.

If you do not care about privacy too much, then there is no problem to accumulate all BTC you have in one address, and that you use same address for every incoming transaction in future.
