how can I cold storage IOTAs?
Remember your seed. That's all - so simple
Will we ever be able to use more than 81 characters for our precious seed?
Dude, do the math. How many possible seeds exist with 27 chars, 81 length?
SO umm, yes then?
My point was: Noone will ever need a seed longer than 81 chars.
Hmmm. Some time ago I was told:
"No one will need more than 637 kB of memory for a personal computer"
not 100% sure but the analogy is if you can guess 81 random characters, then you can just guess all crypto private keys there is, so no point going higher.
