This is always a fun thought experiment/hypothetical. Would you go back in time given you get to keep your current knowledge?
It's tough.. On it's face, it's like "Yeah obviously.. Go back in time, buy as much bitcoin as you can in 2010 for $0.10/ea.. Sell 100 of them three years later for an easy milli, and then cash out a little more in 2020 and be a kajillionaire. GG, EZ."
The biggest thing is, would you be able to do this without going crazy?
Like imagine trying to keep your facts straight in your head. All of the things you know that aren't true, but will be true in the future? How will you keep up? When did Event X happen? Was that 2014? or 2015?
Constantly being tortured by your own weird memory! Is this thing I think to be true actually true? Is it something that's just not true yet? Have I changed the trajectory of time, and somehow made it so that thing won't ever come true? Was it ever true in the first place or am I just mis-remembering?
