Re: GUIDE: Securely storing large amounts of bitcoin (brain wallet/paper wallet)

Brainwallets with human generated passphrases are a bad idea. Doesn't matter if it's offline or online they are just a bad idea period.

This, 1000X this. Brain wallets should never be used, humans suck at coming up with something a computer can't guess.

If we use "sank thou" instead of "thank you", would that avoid dictionary attack?

If anyone else ever did the same and their password was part of a leak, then that password would probably become part of cracking dictionaries.

Also, both "sank" and "thou" are real English words, so they are part of any dictionary.
