No one stole anything from them. Or at least not something remotely close to what is reported. How can 800k btc go missing?

Even people with few hundred btc split them between several different offline wallets. Can't be stolen. Their hot wallet being hacked is a total possibility, but it would contain no more than 5% of their coins. So, they just emptied the cold storage until it was completely empty?

No.

Something else is going on and we will all know soon enough. Don't let yourselves be manipulated like that.
