This is already alarming. And I am thinking...is the security system being implemented right now not enough to deter all of these intelligent hackers as they keep on coming on and victimizing exchanges. The thing is that since there is really a big incentive waiting these hackers are dedicating their great skills, time and money to get into a big exchange and take the coins they can. Now, since we are dealing here with cryptocurrency, once the coin is transferred to another wallet decentralization means that they are already gone for good (unlike with PayPal, I would say!). There must be a solution to this malaise otherwise we might as well go back to the mountain and forget about cryptocurrency.
