You have your own time loop. For one day only: at midnight, if you choose, you can transport your mind back 24 hours and relive the day, but with all the memories you have gained. Nobody else will be aware of this. In effect, Groundhog day.

Given this is there a way of generating bitcoins? Given that the bitcoin process simply uses a lot of machine power to get data, could you take the data back in time? So you could loop many times and come out of it after many interations with a heap of bitcoin data.

You could use the loop for other data processing applications - like the SETI task, acting as a single-user cloud processor over a large number of loops. Is there anything you can do which would be valuable, and, crucially which you could carry back in your memory?

NB I'm deliberately avoiding gambling, stock market prediction and other cheating-knowledge-of-the future etc. The idea is to use the loop to get something valuable which is legal and brain-transportable.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

    $\begingroup$ This is... broad. And opinion based. What metrics are you planning to use to decide which answer is best? Until there’s a bit of work done on narrowing down A: what this time loop is for and b: What you think constitutes a good answer (either of which might give you the answer to your own question) I’m going to agree with Ash and VTC... $\endgroup$ – Joe Bloggs Apr 30 at 15:27

  • $\begingroup$ Please read our meta post about open-ended questions. The problem with questions like this is they are broad, not objective and you've provided no criteria for judging a best answer, making the question primarily opinion-based. You need to convert your request from an off-topic infinite list of things to an on-topic finite list of things. $\endgroup$ – JBH Apr 30 at 15:39

    $\begingroup$ To be honest, I think this could be turned into a great question on the SciFi stack: What TV shows or movies have used a time loop to achieve something. Offhand I can think of at least a half dozen. A search for prior art on the stack exchange dedicated to science fiction might yield a lot of useful content! (Edge of Tomorrow is an example that might be particularly up your alley) $\endgroup$ – Cort Ammon Apr 30 at 15:40
