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 is very strong that even banks are scared on the growth of cryptocurrency in the market and most of the people are preferring to invest on ico's more than placing their money on banks and this kind of speculations for the future are already anticipated by the banks.
