Le problème d'une passphrase générée de façon aléatoire, c'est qu'il est difficile de s'en souvenir et donc il faut la noter quelque part (sur du papier, sur une ou plusieurs clés USB, etc). Et dés que la passphrase est notée quelque part, il y a risque (perte, vol, etc)
Je suis d'accord avec toi mais je pense qu'il faut vraiment éviter les brain wallets. Car en général les gens/sites les génèrent par un simple hachage sur 256bits (SHA256 généralement). Or c'est tres rapide à computer, et des hackers n’hésitent pas à tester tout et n'importe quoi.Voir ce site qui en expose près de 20 000 hackées.

Hi,
As been discussed many times before using a Brainwallet is a bad idea. I ran some test myself and found 18.509 BTC-addresses based on a brainwallet which also has been used in the blockchain before.
I tried to compare my results with the results of other researchers but could not find any lists online at all. I found some examples but not a comprehensive list. So I published my own results over here: https://eli5.eu/brainwallet
Please note: all published addresses have a balance of 0 so this is not a list for robbers
. There are also a lot of extra datasets I haven't used this far so I expect the numbers to go up once I use them as well (I'm in the middle of perfecting my own tooling and blockchain parser so this will take some more time first).
I love to get some feedback and if you have results to share which I missed in this round I'm more than happy to hear from you and include them.

Il faut donc mieux utiliser une seed BIP39 avec une passphrase quitte à conserver la seed n'importe où et ne mémoriser que la passphrase. Car la computation de la passphrase BIP39 est beaucoup plus robuste et coûteuse pour les hackers.As been discussed many times before using a Brainwallet is a bad idea.
