Best term for this by OP is, "Buy and forget"
By doing this, we are prone not to sell our holdings even when the price of Bitcoin goes down a roller coaster. And in this way also we are busy with other things so we can forget to check every time the market or the price of Bitcoin which will help us not to worry or panic just incase the price of Bitcoin dumps.
Before you forget, make sure to preserve your seed phrases properly so that you can forget today and smile tomorrow, failure to secure it, then you would forget today and cry tomorrow.
That is the plain truth, when you keep your seeds phrase for a safe place, you can forget your wallet for long years and your coins will still be save in your wallet and the BTC will rise because you have all the details to have access to the wallet and the BTC inside the wallet. Those people that saved their seeds phrase inside their phone and laptop, we like to warn other people not to do such mistakes because they loss everything when they loss their phone and laptop for fire incident because there is no way they can recover all the seeds phrase they saved inside their phone and laptop.
Security comes first and you'll need to be periodically validating that your seed phrases is still intact where you kept it , so it doesn't get tampered by human actions or natural factors.
you need to be checking the seeds phrase wherever you kept them for security purpose, and to know if they are still safe in that particular place, but if they are no longer safe, you can change location for where they will be safe for future use because the day he or she gain access to your seeds phrase, he or she have control over your coins in your wallet.
