bitaddress.org VS python-slip39

Here's how I do it: Download the bitaddress.org paper wallet web page html by going to this link and hitting ctrl+shift+s : https://github.com/pointbiz/bitaddress.org/blob/master/bitaddress.org.html

www.bitaddress.org is one of the oldest tools you can use the address format is the old format, but it works just the same. You sent to the public key (you SHARE it like your bank account number). Let people know that's your account, and they'll know your transaction history, so keep that private.)

One of the oldest and best is https://www.bitaddress.org

Is there a Bitcoin hardware wallet which is simply a complete product, which I could presumably keep and use for a decade without update? I'm seriously considering holding most of my coin on a paper wallet generated by https://www.bitaddress.org/ at this point.

Is anyone using https://www.bitaddress.org to create their private key? I was about to use it a few years ago and then I learned about ledger. Now looks like I need to find an alternative again...

Sure — with about the same likelihood as selecting the same atom out of all the atoms in the universe, twice in a row.

Besides; don’t. Generate your own entropy, save it as sets of SLIP-39 Mnemonic cards, and use the https://slip39.com App or https://iancoleman.io/slip39/ to recover your entropy (and your BIP-39 Phrase.

Use https://slip39.com

Create a new seed (using your own dice tools to create good entropy).

Practice recovering your BIP-39 Mnemonic from your SLIP-39 Mnemonit cards.

Print out the cards, and decide who you’ll share them with. Send them.

Then, transfer your Bitcoin, etc. into the address printed / QR-coded on the card.

No hardware wallet required; later, use a hardware wallet to recover the account private keys, and use your coins.

Backup your BIP-39 Mnemonic phrase using SLIP-39 [0]

This saves the original entropy from which your BIP-39 phrase was generated, over several groups of multiple SLIP-39 mnemonics cards.

Later, recover enough cards from a few groups, recover your BIP-39, and recover your hardware wallet.

Much more reliable, and safer because an attacker must collect many independent mnemonics from groups they probably don’t know the members of.

Use SLIP-39, and a hardware wallet that allows recovery from SLIP-39 shards (eg. a Trezor).

With BIP-39, you are simply going to lose your wallet, eventually. It's almost inevitable. Either because you lose the 12- or 24-word passphrase, OR because someone else finds one of your backups.

I've written a decent Python implementation, here, which is simple enough to review:
