Money gone 1 minute after release of Hint #7 .... very clever or very suspicious !
there is no goal to spend all this money, so I think someone is running all of this of cheating this is very suspicious.
Exactly, I noticed the eth has been moved out few days ago, probably immediately after the last hint was given. Its either someone has been following the hints judiciously from inception and breaking the puzzles as they come or something mischievous was executed. The puzzle must be very difficult to break no doubt and the winner really did a great job.
