but in his case it's not because it is cryptographically weak. its because after a few years, you won't remember what the steps you did are. unless you wrote them down. which you're not supposed to do with a "brainwallet"...


you could have just eliminated the bip38 part since the final step was just hashing some string to get the private key. anyone else finds any other string with the same hash they don't need to reproduce your bip38 step at all 


and of course you kept notes of what you did because if you wouldn't have you probably would have forgotten those 3 simple steps. and they were very simple. and yet, we all find even simple steps hard to recall after YEARS.
