Difficulty of brute-forcing a seed with missing words?
Difficulty of brute-forcing a seed with missing words? Given a 12 or 24 word seed with one one or more missing words what would be the difficulty of brute-forcing the missing words? E.g. for: one missing word two missing words three missing words By difficulty I mean the number of combinations that would have to be checked against a dictionary. And the related question: how many words would have to be missing in order to make the attack reliably unfeasible? http://ift.tt/2oqwyIY
