We know that bitcoin is strong and all the wallets have milletry grade security but one of my stupid friend today said that maybe someone can hack it with just a calculater because with math and correct formulas we can even predict gambling bets if that is possible then maybe there is any chance of this
you cant 100% predict gambling bets as every game is different and they need to play first before they win and many result will come when they play , I think you can just increase your chances by researching who will play but not entirely you can predict who will surely win. As of military grade wallet security it is still not on that level and the chance of hacking increase when you save information inside your gadget.
