Yea, remember the wordlist BIP39 from which the words are picked, there are 2048 words?
2048^12 combinations possible for 12 words, or 2048^24 combinations possible for 24. 24 lots more secure
But they say 12 words is "safe enough" for now, but I would rock 24 for the longterm HODL wallet cuz I'm weird. Can always swap from 12 to 24 and pay a little network fee it's all good
