Zero wallet: is this a good way to HODL?

Hello,

I don't know whether I am the first one to discover this or someone thought and wrote about it already. I am thinking of using a secure bitcoin wallet app, to create a wallet, write down seed phrase and address, and then buy and put amount of bitcoin to HODL, and then uninstall the app. This way my bitcoin and wallet is only accessed by papers which wrote on them seeds and address.

Is this a good idea?

Btw, this sub seems to be only concerned about memes and jokes, the only posts in this sub that get popular and discussed are either a meme or a stupid joke. Why not try to have discussion about important matters, like tips and notes for using bitcoin (i.e. saving, spending, etc).
