The topic may be strange, but more than once I think what I would do if I could go back in time is the purchase of large amounts of BTC in 2009.
I just wonder if if I had spent $ 20k on them, would it help or hurt. I wouldn't necessarily have time to prepare before such a trip, so I might not know the results of the draws etc - after that, it is much easier then to get the butterfly effect.
Time travel not possible in the natural world without CREATOR doing it(maybe through some sort of Hyper Grace where everyone who messed up in the past are made to start afresh at a particular point and have some bits of memory of what happened in the past. I doubt they will be allowed to jump to/fro the past & future like it's done in sci-fi movies...unless maybe they are at the side of existence where people are not limited by the natural world. That side of existence would definitely be the good side and would be for those who close to the CREATOR. A side where you wouldn't be allowed to cheat to the extent of know what Bitcoin will be worth on the future and taking advantage of the information by investing huge sums of money.
I think people limited/controlled by the world could be deceived in multiple ways, into thinking they traveled through time though. And if Bitcoin was plucked from the tree or isn't scare, I guess they would be given loads of it cheaply, in the fake time travel conditions and told to travel to the future to sell some for higher price.
