Just after I calmed down after being excited about finding the 66-puzzle private key and thinking about how to transfer these Bitcoins safely, I discovered that someone had successfully cracked the private key before me, and more people would be monitoring and  Stealing it, ok, I stopped trying to get this reward, I didn't want the thief to get it too. This is my first and last time posting here to say goodbye to the past year and I will leave this world. I have learned a lot of new knowledge. Best wish to the bounty hunters here successfully crack the puzzle and get the reward safely, good luck.
