Well Wow, If a person can hack a bitcoin network why should he only takes 50 Bitcoins and pays the rest 950 bitcoins to him instead there are many addresses with many thousands bitcoins in it why don't hacker hack it and takes the bitcoins.
it is not possible to hack the bitcoin network. You can hack somebody's computer and take some bitcoin.
Exactly, What i am saying is no one can hack the bitcoin network if anyone can hack it then bitcoins must be dead by now! Also now-a-days people are clever enough to protect their computers from hackers. So its not as easy as its sees.
It's always been rather difficult to hack a computer directly, That's why most hackers attack the weakest part of a computer system. That part between the keyboard and the seat.That's the area that usually needs to be shored up the most.
Coincidently, that's the part almost all computer problems originate from too.
