What was the purpose of this transaction. Why they have paid that much fee? This is insane.
It doesn't have anything to do you with you, why are you asking about people moving their money around? It is said to be a positive woth Bitcoin that everything can be seen on the blackchain, but if Bitcoin was ever really used as a currency, I guess we would have nosey people looking through everyone's transactions and asking what they were for and why the paid x fee!
If you are moving coins between wallets, then it isn't urgent, so you can try to save on fees. Rich people are often prudent, so won't pay more than neccessary.
