Assume that the future can change based on your actions, so any historical information that you bring along with you from the intervening 25 years may quickly drift out of the new realities history.
Edit: also assume that you can be given a healthy 21-year-old body if you want or take your previous self’s place.
Further, identification will be provided for you if you were not born at that time.
This is a great idea but it requires effort and if I were to mine 10billion bitcoin very early, that may change the future of bitcoin such that it never hits 30k+ value per. It seems safer to simply buy 1000 of them at a $0.10 to resale at 10k+.
My plan is minimal effort, minimal impact to anyone that isn’t me, and to get all the money I could ever need.
