the only randomness i trust for my private key

after the coldcard situation, I decided I really don't want to trust any company or third party to come up with "randomness" for my key, which later will turn out was not really random.

So I 3d printed every single BIP39 word to draw from, similar to a lottery. I draw one, toss it and write down the word facing up. The last word is calculated with a fully offline device.

I made the repo public in case anyone wants to print their own (should work on any 3d printer): https://github.com/davidkessler-ch/SeedLottery

edit:
- to mix them up, i first pour them into a large bowl
- it's important to put the words back and mix again, before picking the next!

New emerging Scam alert

Hello fellow Canadians,

I've recently received various phone calls from the RCMP (not real RCMP- however, they are able to change their caller ID to legit RCMP phone numbers).

The caller claimed to have confiscated data from a hacker group and my data was compromised.

The "customer service" from my Hardware Cold Wallet (Trezor, Ledger, etc.) Would call me to make sure my assets weren't compromised.

The first thing that set me off was the speed between the "RCMP" calling and the "Support" follow up call.

Now please don't judge me for not realizing this was a scam right away. The fake police officer had a enough information about me to assume he may have been real and didn't actually want any information from me in return. His caller ID also checked out.

Luckily I wasn't home so I wasn't able to do what this "customer service " agent wanted from me with my wallet. He scheduled a call back. After a few minutes of thought, my alarm bells went off. I called back the real RCMP with the officers name and it turns out he didn't exist.

I messaged the real Cold Wallet customer service and in their FAQs it says "WE WILL NEVER CALL YOU".

In all actuality my hardware Wallet did have a data breach some time ago. My wallet and coins weren't compromised but enough data got leaked for them to target me on this scam. I'm embarrassed to say I almost fell for this and don't want anyone else to.

Please be safe and vigilant. If police ever call you, hang up and call back on their official phone numbers.
