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.
