There always be the rich and powerful everywhere who tries to manipulate and takes advantage everything for profit. This is the reality of capitalism. Whether the name is Justin Sun, Changpeng Zhao, Sam Bankman Fried, Michael Saylor or Elon Musk, everyone like them is out there for profit.
It is not disputed that they are all in the crypto game because their ultimate goal is profit, but the way they will achieve it is important. I would not put Saylor on the same level as Musk, because the former has his own business philosophy and sticks to what he says from the first day he invested in Bitcoin, while the latter did a lot of damage with his tweets by pumping that altcoin, and even greater damage is made by his decision to withdraw Bitcoin as a payment option in one of his companies.
In any case, it is speculated that Zhu Su moved 3 Arrow Capital to Dubai from Singapore to avoid extradition to America for financial crime. This will again be very bad for the image of the cryptospace.
I read an article in which the SEC investigates Kwon, but they already admit that it will be difficult for them to prove that he intended to do something bad - even though he was extracting large amounts of money months before the collapse. I think that in this particular case it would be difficult to prove something, but if you have money and you are not completely stupid, you can at least temporarily evade justice.
it's a stupid amount because it's 5-10 times much more of what you can get from the traditional bank system. 
(e.g. farming the yield, then getting out and shorting $LUNA)
