Do you know who else solved it and took the remaining 0.005?
The lock is opened by your key, which holds another. But where is the second one?
You're nearly done. Don't get board just yet. Stay hungry for the answer: this will help you decipher everything.

This had me puzzled for a very long time. One of the things I considered, was that "the second one" made the tail of "1" look like an address, but that was a dead end.
by your key := SHA-1 hash; second one := placement of the second 1 => 13
don't get board just yet := go to board 13, French local board.
stay hungry for the answer := translate "mange" into English.
This was completely lost on me! I never understood board 13 was French, I couldn't figure out what "Menge" meant, but it looked too much like a word to be part of a random private key. I assumed the "5.00000000" BTC risked from satoshi's feedback meant either "5" as the start of a private key, or "remove 5 characters" which meant remove Menge.
"Stay hungry" to me is like the exact opposite of "Eat". I was only thinking of edible things, but couldn't figure it out until I brute forced the 3 characters.
It was a very nice challenge! And that makes me wonder how you come up with this, I've created small puzzles in the past, but nothing even close to this complicated.
