I would invest in battery tech, and alt energy, then blockchains as well of course. Then I like the global satellite internet concept so I would try to make Bronson and Musk work together so we can get it done soon. Who knows that's a lot of money. I would also like to buy up debt like John Oliver did, and forgive it instead of pursue it. There are so many problems in the world. A billion dollars might not go that far unless your also trying to turn it into 2 billion at the same time
