I want (a substantial amount of) the strength in numbers of a self-custody 24 word Bitcoin wallet, but I don't want to memorise all 24 words; laziness prevails.
My idea: create a note (probably digital) containing n of the 24 words, in order (not scrambled), and to only memorise the n number of blanks. The n blanks will not be in digital form and will be fully committed to memory.
E.g. 8 of the 24 words are left blank in the note:
grab merit ___ can
___ ___ floor car
exit mother ___ festival
october ___ camp ___
trial nephew ___ fabric
galaxy napkin ___ apple
Note: This seed was referenced from here.
Out of curiosity, does the location of the blanks offer a varying number of possibilities? E.g. having the blanks front loaded, rather than spread out?
I'm pretty flexible with this, in the sense of hitting the "sweet" spot with how many word omissions to remember, without considerably compromising the security of my wallet. I'd also consider a wallet/seed rotation cycle every x interval, just in case my copy with gaps is ever unknowingly compromised.
Will this strategy offer a high enough level of protection, practically speaking, or are people already cursing me with the thought of this trade off in security? Pros and cons welcomed in equal measures.
