I have had this conversation before, what is "sufficiently long"?.

Remembering 10 random words in order isn't that much easier than 10 random alpha numeric chars and symbols. The words might have some mnemonic value, but the point is, if you need entropy, don't mess about, use a real private key.

You realise that a 10 word Diceware passphrase is significantly stronger than a 10 character (alphanumeric + specials) password, right?

95^10 = 5.9873694e+19

7776^10 = 8.0828128e+38

Yeah and both are weaker than a truly random private key, I give up, it's only money after all.

[DanBC]

What do you mean by "truly random" random private key?

How much computing power is needed to attack a 7 word Diceware passphrase?
