I am baffled with lot of readings regarding how weak and prone to hacking if you use brainwallet.

But what if I create brainwallet from passphrase using my poem which is nowhere written on paper or on web, its only in my mind and I am quite sure that nobody can hack my mind.

Let us see this poem you speak of!  We can then tell you if it will be secure enough. Roll Eyes

Seriously, Brainwallet is not a bad idea per se but the way people were using it left their addresses open to easy hacking.  I've seen a newer version that forces you to include a salt to make your phrase more secure.  If your poem is unique and unpublished then should easily secure your Bitcoin address with or without salt.

You could do this, but seriously what's the point?

If you had a paper wallet which you stored securely (in a safe or something) you'd be pretty well off without having to remember the keys for years.  If you ever stop using Bitcoin for a while, you might end up forgetting.

The others are correct, just think of it in terms of the probabilities of loss.

How do you lose a paper wallet that you keep with your important documents?

Uhh maybe a house fire?
Heck, even if someone literally breaks into your house, they're unlikely to take scraps of paper.
What do you think the probability of this happening is? Some googling was leading me to believe that the probability of your house burning down was somewhere around 1/3000... And then, usually you can keep a second copy of your paper wallet somewhere else (maybe a bank safe if you're paranoid?).

Are you confident that there's a lesser than 1/3000 chance that you mess up the poem? If you're really really into making a brainwallet from your poem, I suggest you don't write it down anywhere, but also make a password protected paper wallet from the brainwallet's private key. That way, if you forget or mess up your poem, you still have your BTC.

I agree.

A self created poem probably has enough entropy but probably harder to recall than a bip39 seed.

I think what you want to do to your wallet passphrase is risky because anytime you can forgot even one word unless if you are using your poem daily..
To me from 2005 and until now i am using the same password because this password i will never forget it because i am using it daily.. and the password was created when i was a child because i was trying to open one of the computer of my father before and i am shock that i open the one of the computer that until now i am remember that password so i use it and i will never experience of hack activity..  If you are using poem its a long passphrase that i think there is a rate or 50% that you can forgot few of the keywords. .or the arrangement of the your poem passphrase..

I'd be careful with something like that.

If you ever share the poem to someone you expose your private key immediately. It also meanns you will never be able to publish it and the poem will be yours only forever.

Also, if it relates to something about you, it may enable people to figure it out eventually.

Just don't do it. It won't be random enough and it'll be vulnerable, plain & simple!

Refer to my thread about brainwallets and paper wallets for further hints and discussion about it...
