This is almost as iconic as @average_gary smashing a bcash mug on the sidewalk.
I’ve been trying to win a bitkey to smash it lol
Touching grass?
Haters will say it’s fake.
Should double tap, just to make sure the secure element is cooked proper
I used my Q just last night to verify my dice rolls (its still air gapped) so its handy for that at least.
I did a 12 word (50 rolls) and end entered them on Ian Coles website (just for comparison NEVER DO THIS otherwise).
I got the same data (seed words) back from the Q.
I’m keeping it for that and as a decoy wallet. Probably keep 100k sats on there just to see if they ever move. 🍻

Why 50 and not 100? It is not that much more work.
For 12 words/128bits, 50 rolls is all it takes.

With a very robust passphrase.

Don’t trust the Q to verify your seeds. Use Ian Coleman’s offline tool.
Nuke it.

Are we assuming it’s somehow calling home?
Using this method, I verified last night that it is giving identical data back as

A guide on how to verify your hardware wallet’s dice roll seed generation functionality. Arguably the most important part of securing your wealth:
You don’t need to do all this, generate a dice roll to bip39 python script, enter 100 dice rolls and it will spit out 24 seed words. Download the iancoleman bip39 tool and use it offline. You can compare that with Q if you want, the SHA256 sum should be the same but you never know.
Hell yeah

Childrens, please do not try to obtain what he used in the video (a gun), because if you use it you could k1ll someone and commit a cr1m3, and a member of your family (usually one of your relatives) would go to pr1s0n.

But also keep your signing device unwiped and un-updated (move coins to new address created by a better method) because I'm the event of the justice department getting these coins back there will need to be an evidence chain that the coins were yours originally.
