Thank you for the advice, brother. I've figured that myself when looking for the safest way to store Bitcoins in the long term. I found out two solutions: Hardware wallets and Paper wallets. Decided to go for the latter option as it's much more affordable for me. I might consider buying myself a Ledger Nano X later on.
Just make sure to not use those types of paper wallets that require you to just print out your private key and an address. At least one paper wallet site is known to be malicious, it's hard to verify they code of websites. They also encourage you to reuse your address which is horrible for privacy. And they have less error correction, so if it gets damaged, it would be hard to recover the private key.
Instead use a wallet like Electrum that allows you to create a mnemonic seed and write it down on paper, or use something even more resilient, and make sure to create multiple backups.
