For everyone panicking about the Coldcard vulnerability and who is now exploring methods of generating a new seed, just remember there's a lot of flawed ways to use dice – especially d6's. Coinflips are hard to fuck up. You can flip a coin 128 times for a 12 word key or 256 times for 24.
Dice can work but there are pitfalls to avoid that aren't.t obvious.

Just making sure that your method is random and you aren’t introducing any bias?
More that people often use 6 sided dice in ways that make certain bits more common than others.


Generating Seed Phrases with Dice
Making base-2 numbers using base-6 dice is inefficient
Coinflips being binary make them far more suited even if a little tedious, as each bit is randomly generated separately and has a purely random chance of being a 0 or a 1.
That said the dice rolls using Coldcards are not known to be problematic if you use enough. But if you're done trusting anything you can't easily verify by sight coin flips are hard to beat.
Only problem with that is the checksum at the end.
