It's enough for three trips.
One to the future to see the outcome and determine whether or not it was "worth it".
Two goes from the future back to the present to tell us what we found and whether or not we should turn it on.
Three goes back to the past to deal with the narcissistic wealth hoarding parasite who inevitably insists we turn it on despite knowing how bad it'll go in the future, arriving at a point prior to their attaining their power and influence; bonus points if they go back even farther and take care of the parents / grandparents by arranging events which prevent them from ever meeting in the first place.
Granted, whomever takes trip three will get stuck there but, as compensation, they get to take a copy of Grey's Sports Almanac and the 100 year history of the S&P 500 with them. Once they've acquired sufficient assets they're tasked to create an ultra secret organization akin to the "The Kingsman" series of films, which proceeds to deal with all those problematic narcissistic wealth hoarding parasites before they become a problem.
