Wallet was hidden in a Mindcraft structure.
This would actually be quite fasinating. Something like that would imply a virtual structure acting as a stenographic hiding place. Which leads to some interesting ideas. I know the whole, "They don't need your computer, they just need a wrench" idea applies here. But just imagine, a hostile entity (FBI, Robbers, ex-wife) are attempting to take your bitcoins. So, to make a plausible case that you don't have access to it, you generate a minecraft world. Then make various structures based on the bitcoin string and then destroy the wallet. If anyone decides to look at your world, you can make the claim you were attempting art. Which would be hard to dispute, since art is subjective.
