Those who are running long term investment, always have to undergo the active maintenance of seed phase, password, device for instance if your phone lost, you have to look for a way to restored everything into your new device, most people lost their seed phase, private keys and wallets that's why I have come up with little ideas especially if you're this carefree person.
First time to hear such maintenance about wallets and how you'll keep your seeds. You don't have to do that, you keep the seeds/private keys and you're good. Let the wallet maintain itself as it has the devs while you focus on how you keep those important seeds you own.
Once you own bitcoin wallet or other crypto currency, thinking of how long you can maintain your wallet follows this steps,
First send your seed phase or private keys to your emails, also use them to compose a little song only can listen anytime, write it down in your diaries, and makes sure have a google doc to save your wallet keys and other information.
Why would you send it to emails? That's making your keys at risk. You don't do that or else you'll regret that forever when it happens to you. Hackers are also smart these days, they might analyze what these words are that have been sent to an email.
But if you think that's safe for you, good luck but what's safe to me is to never associate it to any email and keep it offline and plainly a piece of paper or a dog tag.
