Are 12 words for seed phase safe enough? What’s the different in safety from 12 to 24 words?
Discussion
12 words is plenty good. Thats 128 bits of entropy.
24 words provides for more, but even at 12 words thats good enough for about 1 billion years of brute forcing. Things may improve over time that could possibly bring it to under 1 million years, but nothing would be cracked within our lifetime
And when the times come, you simply move your stuff to a 24w wallet. Easy peasy.
