Just a little info for people reading this thread. I'm a professional in the cyber security world although I can not say to what degree. These are crackable if you know what your doing, an I don't mean guessing a number and hoping with hashcat. Here is the issue, anyone with wallet.dat that they obtained probably can crack it there self. Let's say that the person has but does not know how to crack. Why sale when they could cut a deal with someone that could. With alot hat said will there be accounts with free coins and tokens on some of the ones "for sale" sure. Some people have realized they can sale a wallet.dat to multiple people because 99% are not gonna be able to crack it. That said if you want to try it that's fine it's your choice just go into it expecting to loose the money you spent on it.
