Spammy, trash "news" site posts clickbait!? I'm shocked!

12 word seed phrases, when properly secured, are perfectly safe. If you reveal all the words, then of course it becomes unsafe. A scrambled 12 word seed phrase has only 12! = 479,001,600 possibilities. Add in the fact that on average 93.75% of the possibilities can be discarded for having an incorrect checksum, that only leaves 29,937,600 possibilities which require you to derive an address and check for funds. This is an easy task on even fairly modest home hardware.

The moral of the story is don't scramble (or do any other weird "tricks") to your seed phrase. The chances are either you will achieve nothing useful, or you will go too far the other way and lock yourself out of your wallets. Just write them down and store them safely.
