Is it really "guessing" a seed phrase if there's nothing in it? Lmao. What he's describing is him pretty much just like generating a wallet. The difficulty is actually in guessing a wallet address that someone actually owns and use.

The guy is just lying, or lucky, Brute force doesn't really work with seed phrases. And I don't understand why he is trying to do it by himself; if he's interested in it he can use some program to try those combinations.

I think I found the explanation in an older post here:

This is not true.
The checksum isn't the last word. The checksum is the last 4 bits.
Each of words include 11 bits. The first 7 bits of the last word have been generated randomly and its last 4 bits are the checksum.
So, if you have 11 word, for selecting the 12th word, you have to test different words until you find a valid word. As I already said in my previous post, 128 out of the 2048 words will lead to valid BIP39 seed phrase.

--------------------

So the guy just created valid seed phrases, means he selected 11 random words and for the 12th word he had a chance of 128 out of 2048, or about 5 percent to get a valid checksum...... sounds quite doable, but of course no corresponding existing wallet with plenty of bitcoins...
