What are the best hardware wallets that I can get to the store may cryptos? But I have a question about the hardware wallet that is, If the hardware wallet will be out of service then can I recover my BTC?
Try to read the thread, especially the begining part. Again, Trezor will be best because it is completely open source, but you should add passphrase while using it to generate keys and addresses which can help against physical attack that can reveal its keys, adding passphrase will make the seed phrase to generate different keys and addresses entirely through salting and the no physical attack will be able to penetrate the wallet.
Hardware wallets really worth to be used, reason being that, the wallets are reliable due to not been connected directly to internet, they can not be penetrated easily.
A reputed hardware wallet like Trezor do not connect to the internet at all, its seed phrase, private keys and addresses are always offline, the reason they are one of the offline wallets.
Private keys being the most important thing to be kept secured in order to avoid loosing fund can be safely saved in an hardware wallets, because the wallets can also have external security pin protecting it even if someone have access to it, your privacy is still intact.
You can not save seed phrase on hardware wallet, the best is to save it offline like on paper, laminated paper, metallic sheet and the likes in a ways it will be resistant to damage and attackers, and best to have like two other copies in different locations.
For Trezor, make sure you add passphrase while generating the wallet because of the reason stated above.
