I wont say that my knowledge of crypto wallets is very high but I can only assume that this problem exists because these puzzles are all held in older crypto wallets that are only p2pkh focused?   So just doing something simple like trying to direct swap your BTC into another currency first before you try sending it to another wallet that you own probably wont stop the bot theft either.  Newer crypto wallet software however doesnt seem to have this problem since people make transactions constantly.   Interesting ideas though from the AI, might try to read more about lightning networks later.  My first thought was to just put all of the btc into a liquidity pool since that somewhat transforms your transaction immediately and then maybe you could just remove it from the same liquidity pool later using another wallet as long as that liquidity provider allows multiple wallets to connect to it.  Many liquidity providers dont allow multiple wallets from what I know about them though.  So you would probably have to do your own research and find one that does if you became the next puzzle solver.   

But if all legacy wallets have little to no security at all,  I agree with what most of you have already said that its probably hopeless and no way to move the funds.   I am just surprised by this because I thought most crypto wallet software also had options that stopped frontrunning attacks or any type of bot attack for that matter.  Usually such options would just enabled in the wallet settings with a checkbox next to them.  But I have only been involved with crypto for about 1 year so I still have alot to learn,  lol.   Just some of my random thoughts about the situation.  I am more of a crypto investor so I dont mess with coding nearly as often as a fulltime programmer would.    I was often trying to solve puzzle 66 though for about 3 months until that was solved so now I just keep trying to pick at 67 now whenever I have some free time.  I prefer to use python code mostly even though I realize that its not the fastest and its probably putting me at a major disadvantage.  I just overall find it easier to work with the different crypto modules or libraries in python compared to some of the other programming languages.
