I would advise against using paper wallets though. It would be better to store your private keys in a USB stick or computer that never touches the internet. When you are ready to spend (some of) your bitcoin, you can sign the transaction offline.
If you are going to import your private key to a wallet on a permanently airgapped computer, then it is no more risky using a paper wallet than using electronic storage. If I'm planning to store a wallet for 10+ years, I don't want to be concerned about hardware degradation or failure which could corrupt my wallet file in that time.
You increase your risk when using a paper wallet versus using a wallet stored digitally. Regardless of how the private keys are stored, you have a set of risks when creating a private key on a computer. When you move that private key from your computer to paper, you have to incur additional risks.
