Planning also to buy one in the next few days. Just wondering if I can change Bitcoin adddess and generate new private key with that hardware wallet? What if I loss it?
What if you lose that Nano? Nothing special, you'll buy another one for $70 and restore the new one with your seed. If you want, you can have a few, and you can put it into safe places, but what you really need is to protect your seed.
You will quickly adopt to it, it's easy to use it, it's not like brain surgery
You don't need a PC even, if you have an Android phone with mycelium, just be sure that you use the legacy bitcoin wallet if you want to use mycelium, because the app doesn't see the segwit wallet of the Nano
