You do not need to go back to the past, instead, you can try to think of the future. Just like what @OP is trying to say, we can assume that the current year is the past year and the future of 12 years from now is the present. This mean, we do not need to have a time machine but instead, we can just start accumulating Bitcoin at the current price and wait until 3 halvings had passed and see for ourselves that we had made the right decision of accumulating Bitcoin 12 years ago(present year).
We must anticipate the future by acting now before it's too late. Even though Bitcoin has reached a high level of mainstream adoption during the years of 2017 and 2021, there's still a lot of people who haven't heard about it or used it before. Once the whole world adopts Bitcoin as an alternative to traditional Fiat currencies, market prices will never be the same. They will be a lot higher than what they are right now.
I'd say we're still early adopters of the future of money. Just keep buying coins while they're cheap to sell them at a later time for profit. You can bet BTC will get past the $1m range after a few halvings. Goldman Sachs already declared Bitcoin as the best performing asset of 2023, so the best is yet to come. Who knows how far will the cryptocurrency go? Just my thoughts
