I've a hard time not to judge such a sort of obscene transaction. How much good could've been done with such an amount in many countries of this world?
I don't get it why people do this, be it countless small and the few huge amounts of recent time. The "countless" small dust coins bloat the UTXO set, the larger or huge transfers are what exactly? A show off of the filthy rich? I don't know... what's your opinion?
Yeah I also don't really like how they're throwing away Bitcoin under the guise of donations. It's basically like burning it, not donating it. Ideally donations through social organizations would be much clearer, more useful, and more accessible to those who really need it. But in the end, I know it's their money, and they have the right to use it for whatever they want.
We can't dictate that.
