I hope the money will be put to good use. Thank goodness that many people who become multimillionaires, think of others and help them as in this case. I make some donations too, on a small scale and as I increase my net worth, I will donate more.
Reading the news from various parts of India, it seems like a really good deed from Vitalik because India is going through the worst time the country has ever seen. There are almost 1 million cases a week if not more and the number don't seem to cease anytime soon. The government in India has already collected massive donations and I just hope they are not going towards pleasing the leaders.
This will boost Ethereum's popularity with Vitalik doing humanitarian effort and 1 billion isn't a measly number that you just donate, I am sure that Vitalik thought of it thoroughly. And not to mention that this donation is also useful for him since it will be tax exemption for him.
He could have easily invested such a big amount in any upcoming project but really nice on his part that he decided to donate instead of investing it.
I am not entirely sure who managed the India-Covid-Relief funds which are sent by Vitalik but I hope they are in safe hands because corruption is one of the biggest problems after corona virus in India.
