Mass hack -- over 1000 bitcoin addresses have been affected

[ranochigo]

for the life of me I do not understand why any trusts a computer for a seed.

It's certainly a complicated topic. Rest assured that it is a topic that is heavily studied and there shouldn't be any concerns about using it so long as it is securely implemented.

There was an extensive discussion on this: https://bitcointalk.org/index.php?topic=5460240.0.

are the 2 machines perfectly random not likely

but they are very likely random enough that no one will be able to understand the lack of perfect randomness for those 2 machines.

Even if they buy 2 of the same make and model.

Since they likely not perfectly identical even having 2 of the same units won't help much.

In fact if you have a lot of coin buy 4 separate bingo machines from 4 different companies.

Yeah, they are probably not random. The QC on these aren't as stringent as you think. Any difference in the size of the balls would result in certain results being more common as others. It really doesn't matter how unpredictable it is, any degree of randomness below that of your computer already means a weaker seed. I wouldn't trust a toy for my security. Besides, you have to consider the checksum for the final word, and BIP39 also only allows for 24 words at the maximum, anything beyond that is not within specs (even if it is in multiples of 3s).

The best practice isn't to use a bingo machine, but using an unbiased 6 sided casino dice, generating at least 50 rolls.

not against using a six side die but how do I insure the picking pattern?

it is easy with 2 bingo machines

32 in one machine and 64 in the other. allows a 1 to 1 match for all 2048 words.

not sure how to assign the die rolls properly to the 2048 words.

is there a demo on youtube?

Nope, but you can use some simple math. BitBox has a nice lookup table here: https://bitbox.swiss/bitbox02/BitBox_Diceware_LookupTable.pdf.

ColdCard has a python script for you: https://coldcard.com/docs/rolls.py. ColdCard converts your input to SHA256 hashes before continuing with the word assignment.

Generally, if you have two different methods of generating randomness, and in your case two different bingo machines with different number of balls, you're bound to have certain values occurring more frequently than others.

Flipping a coin (or throwing a dice) enough times is a lot more compact.

You don't select words, you select bits. The easiest representation I've seen is Bitcoin Visual private key generator. This creates a private key instead of a seed phrase, but the principle behind it is more or less the same. Note that this visual generator is mostly for educational purposes, you shouldn't use it for actual funds unless you know what you're doing.
