This sucks, I see stories like this all the time on here. He really shouldnt have been keeping that amount of crypto online though. It should be on paper wallets or a hardware wallet. Sad for him 
Yes this huge amount of investment should be kept in a safe place .The question is why didn't the investor make sure that his investment is safe?
Hardware wallet is only a cheap investment to secure all of his crypto so why didn't he bought it if he would keep a huge amount of crypto?
That's really sad to hear that there's a lot of investors who are in depth loss and not only a thousand dollar but a million dollar which cannot earn that easily especially for normal person like us, if hat will happen to me I really don't know what will happen to me, maybe I will be in deep depression or will just let it go if I am billionaire. Anyway, we should always let this be a lesson to be learned from all of us.
