A bit of background about him here:
https://royalfamily.org/royal-family/hrh-prince-philip/To summarize, Prince Philip of Serbia was born in 1982, so he's relatively young, and is currently working with a global asset manager in London.
At a Serbian TV talk show, he mentioned a few things about his job:
"I analyze and mainly tell clients what happens with the market, what’s going on with their portfolios, and I speak with a lot of other analysts and a lot of other portfolio managers within the company. We help to make decisions … It’s a great experience to be an analyst. I learn a lot."
Interestingly, it seems that he has indeed learnt a lot about Bitcoin. This is what he mentioned on TV:
"Well we need to take the money away from the state.
Especially since that last financial crisis in 2008 when the extraordinary stimulus has been pumped into the economies. And since then with the Corona pandemic, unprecedented amounts of stimulus have been pumped into the economy and, of course, where is this money going to go? It’s going to create inflation.
I think we need to have hard money again. We need to have good quality money that’s not subject to inflation.
With Bitcoin, you don’t have the freedom to keep printing. You have a cap of only 21 million bitcoins that are going to be produced. Therefore it’s never going to be an inflationary asset and this helps to protect people.
And he also mentioned how Bitcoin is not tied to any country in particular, and how it can provide freedom to people:
"Bitcoin is freedom, and this is something I want for everyone."
Given that he's giving financial advice to people at his job, I think this is really interesting, and will probably end up with more people understanding Bitcoin better.
