Someone with that amount of Bitcoin? There is no way they would store on their mobile phone in an exchange or on a samsung phone. This has to be fake. How on earth could a whale let this happen in such a hacker driven environment around the space? I don't believe this.
You have a point though, but, nobody can tell what exactly happened to him as such amount shouldn't have be kept into online wallet. The victim might be those who haven't interested in the knowing of this technology but rather love to associate with the investment involved.
the title says crypto whale . whale means expert on this field so i dont believe that he arent aware of the risk plus not only him but many pro and big hodlers do also got hacked no matter how they secure thier accounts . thats only an evidence that hackers are smarter than the users of the wallet and exchanges because they know how to bypass any security without us knowing it and they mainly target big people because me i havent been hacked yet luckily as im also a small time cryptoer
