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
How could he hack using a calculator it doesn't mean that Bitcoins deals with numbers it is hackable using a calculator lolz. I agree though wallet is hackable cause it depends to the person who keep it if you are not properly keep your private key then you are prone to be hacked but for bitcoin in blockchain it is impossible because it is decentralized and no one controlled it. Your friend maybe a day dreamer who want to be an instant IT expert.
