I was going to say 100K in 2017, but now I'm leaning toward the billy in 1917 and all the things I can "invent"
I'll create the NBA with the 3 point shot already in
I'll play the Still D.R.E. beat on the piano and have audiences 
I'd bet 500 mill on Jesse Owens and bankrupt Hitler to a point that they couldn't fund a war

I can fund a lot of technology back then to speed us up to where we are now sooner (IG thots by the 1970s

)
I would have to get women to make a habit of shaving/waxing their legs and bushes though
