HAHA I'D BUY ALL THE BITCOIN FOR HALF A CENT AND I WOULD HODL FOR YEARS & LOL SELL STEEM AT THE TOP LIKE NED DID!!!
jkjk
I would go back to 8th grade and confess to that girl that I liked that I knew liked me back but I never did it or I would probably travel back and attempt to save my friend that died surfing in June 2013... but that would probably create wacky time issues or alternative timelines...
or better yet, use the time machine and hope I explode into a nuke somewhere where I can do the most possible damage to the world... so probably blowing myself up in the panama canal or the suez canal, for well, fun. or the Artic/Antartica? I think I watched a video about how you could destroy the world by blowing a few nukes up there or down there.
hmm, going back in time to explode was not the answer i expected at least :D
I think the video implied that there's already a time traveler among us doing these things.
The only human that we know has been tru different periods doing who knows what.
The video was just telling us Keanu's plan all along. He is the God Emperor of Time.
