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
Bitcoin works on a secured block chain mechanism.Wallets are well secured.Nothing would happen nas your friend imagines.If it is true,then no none would be having their bitcoins in their wallets and every bitcoin would have been hacked.
This makes no sense - what does Gambling have to do with Bitcoin itself? There are HUGE thefts around the world probably every hour in USA.. does that make the USD dangerous? It's the gambling website owner's fault if he didn't allocate enough money to provide the website a good enough security. And most of the big BTC hacks were actually scams, and the "hack" was just a reason for them to be able to carry the millions away. People are getting rich from these "hacked" reasons... wake up!
EDIT: I might have understood the message the wrong way. If a computer can predict a gambling result with math formulas, it makes it pretty ... impossible .. to crack a private key. That's just one private key. What about all the private keys around the world?
It's hard for a hacker to crack a password, even if it's a 15-character one. It's hard because the computer needs very much time to crack it. And even if computers are evolving, it will NOT be too easy too soon. I doubt even a quantum PC can bruteforce a private key at the moment. Bitcoin has been here for 9 years already, and no such event ever happened. The only "hacked" people were those who left their private keys on their desktops or somewhere hackers or thieves could easily find. It's a mistake.
