But I'm curious to see the solution.
Is it possible to post the solution and a brief explanations on the harder ones?
Here's the solution: 5JVAAm4A1rxDB5boKURLyfbVxNj9cVZSGdYx6AEg1VB7aP9ALSX
I can explain any specific clues/characters if you like.
Unfortunately I wasn't the one who solved it. I kind of gave up yesterday, after I was stuck on few questions for so long.
Hmmm... This is what I was hoping wouldn't happen. Whoever solved it needs to comment here so that everyone else can trust that I didn't take the money for myself. Without this trust nobody will donate to the next puzzle and the winner won't have a chance to win any more BTC... So it makes sense for the winner to announce it!
