How can I save my seed phrase?
I have heard that many people carve their seed phrase on stone. And they use different techniques to save it. If someone else gets 2 or more of my seed phrases, will it harm me? How can I make my seed phrase more secure?
Do it offline. I don't think you can be sure enough about the security if you created the seed phrase online.
Usually, install a fresh OS + the necessary seed generation tool, wallets... and finally save the seed. I do everything offline, and after all, I destroyed this session.
