Then again, why the fuck do they want to burn money for nothing?
Maybe because they think money can't buy happiness. Or, maybe they have lots of bitcoins, it's just like rich people who have a hobby to burn money at the party. So, as I know when someone sends bitcoin to op return that makes the bitcoin supply decrease, which makes the price to the moon if demand increases.
