If you remember bitcoin's journey, I think many people regret not being able to make the most of that time, but the past can't go back. And for another reason because bitcoin is not easy to predict and only long term can give such great results.
we can start from now and hope time can repeat itself and even though the price is now very expensive we can buy it gradually with every drop and buy according to our ability, bitcoin is a future that has the potential to bring good and happiness on future journeys. So it's never too late to repeat the past because the future is long and most likely the past will repeat itself and don't waste it.
and many people do not believe in the magic of bitcoin and even those who used to hate or distrust it are more devastated and regret it more.
