i got 24 word seed for my ledger nano s. And i split it up on two papers.
21 words on one paper and 3 words on the other one.
Lets say my 21 word paper would be exposed. Would it be hard for the persona that has this 21 word seed to crack the wallet ?
thanks
No. It'd be fairly easy (if they could work out what it was of course).
Your best bet would be to go with 12 words and then the other 12 words (if you input them the wrong way, it'll be rejected by the ledger nano anyway.
