I've placed 0.0002437 BTC in the following wallet address:

bc1qe6tm9gg9gzazfqh994eycv977cl8tw83a8g373

The seed phrase used to generate this wallet address is as follows:

symptom few lift suspect hire visual oppose sustain merge drastic salmon require

There's only one catch — I've put an additional passphrase on top of the wallet

I'm curious to see how long it will take for that passphrase to be cracked by brute force

For now, I will not give any details about the specifics of the passphrase, other than it is one 'word' long

If, after some time, there is no success, I may decide to reveal how many characters long the passphrase is

But for now, there's ~$15USD worth of bitcoin up for grabs

Have at it

EDIT 1: Okay, so in my haste when generating this wallet with Electrum I forgot to change the seed type in the options menu to 'BIP39' from 'Electrum' so the seed is an Electrum/Segwit type. It restores just fine

I think the passphrase does have a bit too much entropy, though, so here's the first hint:

The passphrase is 20 characters long, no spaces, and contains the special characters $ and ! – no other special characters

The total balance has also been increased to 0.00032855 BTC thanks to /u/flibux

EDIT 2: Alright, I'll reveal some more hints. I suppose this passphrase has quite high entropy

The passphrase contains the letters y, g, r, and n – there are six other additional letters not yet revealed. There are only ten total letters in the passphrase

Also worth noting

The total balance is now 0.01032855 BTC thanks to an anonymous third contributor

EDIT 3: Another hint. I suppose I was a bit misleading when I originally said that the passphrase is one 'word' long. I didn't do that intentionally, but realize it was a bad way to describe a password/passphrase that had no spaces in it.

• No spaces = one 'word' * was my initial thought process, which was confusing and perhaps incorrect

The passphrase is a sentence between two and twelve English words long. No spaces (which is why I initially described it as one 'word.' Sorry for the confusion). Some letters in some or all of the words may or may not be replaced with numbers or special characters.
