       | I once generated a Bitcoin private key with a SHA-256 hash of a
       | pop song lyric. Within 3-days the roughly $100 I sent to that
       | wallet, as a test, was drained.

       | Entropy matters.

       | 
       | 1) "half" is six words you memorize
       | 
       | 2) "other half" is a long annoying non-memorizable string that
       | must be written down?
       | 
       | Am I missing something?

       | phrase, a border wallet puts Y bits of that into the grid and Z
       | bits of that into your memorized pattern." This would make it

       | seed phrase (Z bits worth).
