Your money is safe only in your wallet and if you are trader you agree with risk that you might lose your funds. Remember that.
Hacking is actually one of the biggest threat to all those who are there in the world of crypto currency as their money is highly exposed to hackers and there are hackers which are continuously trying their best to grab all your coins. Till the time, you will not be having enough of knowledge about the things and that you will not take care of your coins well, there will always be a risk of losing of money.
If I have money and I am not making use of it because of the attack from the hackers, then I think the attackers have successfully done their job by keeping me away from my money.
Too much trading is not the problem but the problem is using the public computers and leaving your information in those computers. If all the bitcoin holders stop using the computers of others, I can guarantee that the hacking will fall down 50 percent, because this one thing is the most dangerous thing over every other thing.
