If you had the ability to time travel, what era or moment in history would you most want to visit and why?

I would most want to visit the near futures. Go, quickly look up various market timings and big money movers. Go back to present, invest.

“Retire” from my job, use my time travel to become a billionaire.

Also, I can know future disasters and geopolitical upheavals, that way I can move to the safest areas of the planet before each major situation.
