Is it true? There's a possibility that this is false news since many people wanted to down BTC.
It might result in drastic changes since whales have a great factor in the flow of the cryptocurrency market.
Even if you have expertise in cybersecurity, hackers can get what they want especially if it's a group. That's why it's one of the disadvantages once crypto was adapted to be the main currency or use it as a huge business. One of the results also, people will give negative thoughts about crypto regarding this situation.
We don't know, just take this post with a grain of salt. There's no way people would donate to that guy, he's a millionaire! but pretty clumsy with his security. It's just that if this is true then there's a potential for the market to tank soon when they start selling Bitcoins and BCH. This amount is not a joke, it's pretty huge.
Maybe this was a way to avoid any tax for that huge amount? possible in my opinion.
