I think one of the best ways to store #Bitcoin is @COLDCARDwallet.

Here is a strategy for max security.

1. Use it air gapped.
2. Download and verify latest firmware (use firmware from a few months ago if you don't review the updates yourself).
3. Generate seed using dice rolls.

4. Store seed on @blockplate.
5. Export your "watch only" wallet to microusb.
6. Import your "watch only" into software wallets (I like @ElectrumWallet and @bluewalletio).
7. Make sure the receiving addresses match the receiving addresses visibly on your Coldcard.

8. Send a small amount of Bitcoin ($5) and view the confirmed transactions on your software wallet.
9. Wipe your Coldcard device's seed.
10. Use the same device or a completely different air gapped Coldcard to recover your seed.

11. Send your small amount of Bitcoin (from your software wallet), and use your fresh Coldcard to sign the transaction.
12. Broadcast the transaction on your software wallet.
13. Verify the transaction has been sent and confirmed on the blockchain.

Now you can be certain that this seed was generated entirely through dice rolls, has never touched a device connected to the internet, and was backed up successfully on steel that is both fire-proof and water-proof.

Additional IMPORTANT rule:

NEVER type your seed phrase into a computer. Your seed phrase should only be recovered into Coldcard devices themselves running verified firmware.
