It's great that he already recognized what bitcoin can do to inflation, but it will be better if he can use his influence (though little) to make people be aware of the positives of bitcoin. He came from a financial background, and sure enough he knows what he's talking about. All he needs now is the drive to let other people know of bitcoin, and educate them enough for them to make the switch, or at least consider bitcoin as a part of the future monetary system.
I think that the decision of that prince is very intelligent, because since BTC is totally deflationary in nature, it is the only way to combat inflation, which has been the biggest problem and vulnerability of any traditional economy. Some countries with very high inflation rates such as Venezuela, Argentina, the few people who know BTC can assure that their particular economies have improved remarkably compared to the average where they live, if the price of BTC drops in price it does not matter, it is still higher because making the change to local currency or dollar or hard currency is still something very attractive and improve your life.
