Well, Nikola Tesla had just as much insight into potential future impacts of certain techs and had comparable levels of impact on the world with his inventions (he could have had a lot more impact if he werent drowned by capitalism, eg his free electricity transmitter).
Tesla never claimed to be a TT, so if human genius can be as capable as he was, then I think Bitcoin could be achieved by a similar person without the need to 'know' the future.
That said I hope he is a TT, its way more interesting and also that way he less likely to spend his coins for a loong while:)
The other thing about TT is that it begs lots of questions i love to think about:
is TT not regulated in the future? Was [t]{s}he[y]* a lone shark traveler just out to make themselves rich with pre-mining?
If TT is regulated or not, why didnt * go back and kill hitler or some other mass monster(s)?
Why not prevent lots of senseless deaths by inventing earthquake detectors or leaving more benevolent tech?
If * are just out to get rich, why not do something that is more likely to survive into the future like buy gold at 1$ per ounce(gold has stood longer test of time so far, BTC could be made illegal still in an unknown timeline - I guess this person cant be from a tooo distant future then)?
What other inventions were given to humanity without knowing who * is/are? If this is a solo actor acting illegally, how did they get away with it? Surely they can detect ST distortions?
Maybe * illegally travelled back, pre-mined enough to get rich without intending to return to their original time for fear of getting busted - but that would mean the BTC value gets high enough in this lifetime, and adoption gets widescale enough that * can withdraw them without causing a price crash, OR widespread enough that * can just live off spending them...
Now you got me thinking:p
