I think we all regret not getting into bitcoin any sooner, but the truth is that even if I knew about the existence of bitcoin when it was not worth as much, there is no guarantee that I would still have them, maybe I would have sold them, or maybe I would have lost them.
Everyone will surely agree that the most frustrating thing is not joining bitcoin at the start of the launching time or at the beginning of the year. If you buy that year you must be rich now. I'm sure many people are getting rich because of the exorbitant prices at the moment
