Damn, looking back the Mt. Gox really the worst cryptocurrency exchange hacks with 850k BTC. Nothing could surpass that amount and when I saw Binance on that list with 7k BTC loss, really nothing is safe in the internet.
My Friend, there is nothing secure, we should just take precaution. If someone can avoid being hacked, then why do these companies lose so much money and reputation?
Newer research found that some of those hacking were done by the mt.gox themselves. They were hiding the users coins and filling for a bankruptcy. Mt.gox ended a scam. Mintpal too was closed after the 2nd hack. Though the site let users to withdraw their funds, some accused the site of not letting them withdraw.
