Some crypto wallets use a 12 word seed, other use a 24 word seed... Some hardware wallets, even those that support 24 words seed will default to using a 12 word seed... Some even let the user choose at the beginning (Safepal, Electrum)... What is the difference and does it matter? A quick look at the difference in entropy, the impact for those who do split or scramble their seed.

If you are new to Crypto, my suggestion is that you start with buying ~$150 worth of Bitcoin, Ethereum, Litecoin @ Coinbase and get familiar with storing it, moving it around, etc.
For your first purcahse, just stick with CoinBase: www.coinbase.c...
For Trading, just start with Binance: www.binance.co...
By sticking with large, reputable exchanges for your first purchase (Coinbase) and first trade (Binance) you can avoid getting scammed right at the start by purchasing a non-existing coin off a scammy exchange. (You would be surprised how many people fall into this trap)
Don't have a hardware wallet?
Be safe and buy them direct from the manufacturer. (Not just through some random on eBay, Amazon, etc)
Get a Ledger: shop.ledger.co...
(If you are just starting out, I would just recommend a Ledger Nano S)

So, if you are a safe person and you know the ins and outs of when to use the seed, and you protect the seed by not sharing any part of it with others, then what's the issue with 12 words? And, if you apply a passphrase to the 12 words, haven't you completely mitigated the issue? I think this is really more about how to properly secure the seed so that you can use it when needed but also so that its not easily usable by thieves. I think the best approach is a passphrase that is not stored with the seed. In fact, ideally its a passphrase that is never written down at all.

One of the other factors that I don't cover here which has increasingly been an issue is the checksum on 12 word seeds is really weak. Basically you can have a mistake and still have a 1/16 chance that it checksums correctly as opposed to 1/256 for 24 word seeds.

12 seed words is enough. The odds of someone guessing 12 seed words in the proper order out of 2048 words is a 40 digit number to 1! 1 quintillion is only a 20 digit number. Guessing 12 seed words in proper order is like winning the lottery and being struck by lightning at the same time

The best reason actually isn't covered in this video and that is the stronger checksum that 24 worss gives you... The checksum on a 12 words seed is so weak that you can swap two words and have a 1/16 chance of the checksum being valid. (Compared to 1/256 for a 24 word seed) A strong checksum makes it much easier to identify and resolve errors in your seed transcription... The other reason is for folk who roll their own entropy, basically if you are using something like biased dice, it actually ceases be an issue once you get up to 24 words. 24 is more secure when folk do things like splitting, scrambling, etc. (and is also secure for the Trezor "standard recovery" whereas 12 is not...

Forget the words. The words are just a representation of a large number. For 12 words that number has 132 bits (128 + checksum IIRC). That means there are 2^128 possible numbers, or 1 in 2^128 of "guessing" the same number. However that assumes a perfect random number generator that provides a uniform distribution of random numbers. That's unlikely to be true. It doesn't change the math very much, but figure 80% uniform instead. That reduces the space from 2^128 to 2^102, or the equivalent of dividing the possiblities by 2, 26 times. (Dividing by 2 twice means you have 1/4 as many, divide by 2 again and you have 1/8 your starting possiblities, etc.)

I only wish that my trezor model T allowed me to make a 24 word seed. Because it has a screen and the word never once appear on the computer... they consider 12 secure enough and only give you that option... I also permanently imprinted the seed into my HODLR disk cold storage device ($150 but so beautiful and functional) so I dont wanna simply transfer my coins onto a 24 word seed address, rendering my HODLR disk useless. In the future I will buy another HODLR disk and create a 12 word but for now I'm stuck with my 12. On the plus side, I can easily memorize 12 words in case I need to smuggle my crypto into another country lmfao! BUT... I do have a passphrase that's like 50 characters long... so technically my seed is 13 words with the 13th word consisting of 50 letters. That's gotta come damn close to 256 bits! Edit: I just found a passphrase entropy calculator and I learned that in total, my 12 word mnemonic plus passphrase has 298 bits of entropy! Still wish I had a 24 word seed though because then I'd have 426 bits lol. USE THE PASSPHRASE FEATURE PEOPLE! It's future proof

Is this verification step only meaningful for those using electrum as their main wallet? In other words, if I only use electrum as a tool to setup my trezor device so that I can have a 24 word seed phrases, and I will only use trezor wallet from that time on (with trezor GUI), do I still need to worry about if the version of electrum I download is the real or scam version?

That's correct and it would be nice if it were that simple when it comes to seed length, but engineering doesn't work that way. For example, do you know what a checksum is and how strong it is for different seed lengths? (Or different schemes if you include SLIP39) Are you confident that data you selected on the input is actually 128bits of entropy? (If you used a TRNG it's probably fine, but if you used dice then maybe not)

@@CryptoGuide The checksum's length in a seed phrase has nothing to do with securing private keys. It's purely for integrity verification. The actual security lies in the seed's entropy, which is robust against brute force attacks. Claiming otherwise shows a lack of understanding of how cryptographic security works. Saying TRNGs are more reliable than dice rolls is flawed. Physical randomness from dice, when done right, can be more trustworthy than a potentially faulty TRNG.

Integrity of you backups is part of security of your overall setup, so I'm glad that you at least understand that such a thing exists. The issue with BIP39 is that the checksum strength is tied to the seed length, so 12 word seeds are extremely error prone. (Though this problem is resolved in SLIP39, so the 128 bit share groups are fine) Dice are better in an ideal world, but both compensation for the base conversation with dice and accounting for dice bias is basically an unknown, but if you do enough rolls for 24 words you have more than accounted for both and can be confident that you still have more than 128 bits of real entropy. There is no disagreement that 128 bit keys are cryptographically secure, but rather a question of what is best once all the factors for creation and use of a backup set are considered.
