If you had a time machine...

[madhatter.]

If I have a time machine I'm going to the future by now, In the future humans will be immortal.

That, or dead. Maybe AI's will take over the world once they are developed enough and there are no humans around. Or some other extintion scenario will happen. The future can be a dangerous place.

I went back to 2010, to buy bitcoins.
2040， I went to see Bitcoin how.

[bitbunnny]

I would just jump into tomorrow

[krunox123]

I would go back to the time where I did not invent time machine.

I would probably travel back to the 1920s and make sure that Tesla's inventions came to fruition rather than being seized by the FBI upon his death never to be seen again. I truly believe his inventions would have changed the world as we know it.

Tesla was a gift to humanity...  Our rulers will destroy anyone like him nowadays usually with regulation to make the merica a "safer" place.

I am with this idea however I cannot see how you would pull it off .

What will you do if you had a time machine that could go to the past and the future. But you can only use it once. (ie. you can't take the time machine with you)?

Be sure not to end up in the past with notes printed in 2014...

I would go 5 seconds ago, slap myself, and see how much it hurts 5 seconds after getting slapped.

Go to past & kill justin bieber

Go to past & kill justin bieber 

Why not kill him now?

I'll change my answer: I would have gone back in time and worked harder. But it's not too late now. I'll work hard now too.

You work twice as hard, your 10 year old can be one's 20 years, and if you are doing three times harder, you can compensate for even more years!

[sandykho47]

Go to past & become bitcoin early-adopter

Are you sure you want to work harder? Work smarter instead.

Working harder is working smarter.

Go on Noah's ark and kill the two mosquitoes

Go on Noah's ark and kill the two mosquitoes 

There they are, riding the tyrantisaurus rex (or is that his wife?).

I would go back to 2008 and start putting any CPU I could get on mining Bitcoin.

I would also have taken different courses, and would have studied computer science and economics. We are on the brink of a crisis and I believe that cryptos can provide the solution, and I feel severely lacking in the skills to contribute. Its also the reason why I got sold on Daniel Larimer's vision and got involved in Bitshares.

Being an age-old fan of Back to the Future (the trilogy), I have the occasional Marty McFly type dream.

Maybe I could go back 50-odd years and somehow marry the lovely lady I had a crush on in my high school days (my then best friend's Mum, P.H. (1944-2009), God bless her soul; linked photo is taken from the public domain). But in that parallel universe, my best friend couldn't then exist (!) and we couldn't have that. Also, life as a coloured person in the 1960s (in a majority white western country) wasn't necessarily always all that flash, even if the music sounded much better than most of today's filth.

Being able to use the time machine only one time poses an interesting dilemma, a very different situation from the BBC TV show Goodnight Sweetheart with its time portal, the novel 11/22/63 with similar, or of course Back to the Future (1,21 GW a prerequisite!).

[Stevenirving]

Obvious answer. Invest life savings in bitcoins at a couple pennies per btc.
Sell at the all time high. As it is only a handful of years this would give me access to the time machine again. As I would only have to wait a few years until this moment again. I would take the cash with me and do it again. Making certain all of the bills I pull out at the all time high are pre 2008 bills just to make certain no one will be able to be suspicious. Then when I repeat the process I would be the richest man alive.

I have thought this scenario out a million times.

I had a time machine many sad events that happen in my life will provably not happen. I go to the future find a cure to aging, bring the all new technology with me to the past when I'm still young.
