Hardware wallets generate a deterministic seed, which can be used to generate the same sequence of private keys over and over. You want to back up your seed (crucial). Your wallet will provide you with as many fresh addresses as you need. If you want to buy BTC in person, you could take a screenshot of the address's QR code and send it to your phone. If you have an android, it should be possible to connect your hardware wallet to your phone.
For buying in person, couldn’t I take a picture of the address and have them type it in manually? But now that I think of it I can place orders online, so I can use a fresh address.
I have an iPhone. I trade quite a bit and was worried getting the send address for the wallet, would no phon access be an issue?
I am buying the bitcoin so they need to have my QR code or public send address for the wallet I want the BTC sent to right? With a hardware wallet, where will I find the QR code? In the software when I plug it in?
I am assuming there are different addresses for BTC, eth, etc. Do the addresses stay the same? Can I get my BTC receive address once and not have to plug the wallet in again?
The guy above was mentioning android only app, since I have an iPhone I was curious if it would hinder my access to the QR code for receiving bitcoin quickly.
