No need to regret it when you see the price of Bitcoin that is getting higher because you can immediately buy it when you have some money that you can use for it. And now you or anyone else is also not too late to continue making purchases on Bitcoin with their own money because from several cycles that I have seen, Bitcoin always increases by making a new ATH after a price correction in the market. So you don't need to have regrets about the price of Bitcoin because when someone can afford to buy the best asset like Bitcoin, they should be proud even though the amount may not be much because it depends on the level of each person's ability.
In other words, don't regret the past, but regret the future if you don't dare to buy bitcoin today.
But however, each of them will definitely consider many things before investing, especially if they really know how bitcoin performs between two different cycles. The current entry point is too high for most people, but there will always be people who don't care what the price is because they just want to buy and hold it for the long term.
There is a good strategy to buy bitcoin now and that is when bitcoin is experiencing a correction. Buy dips and hold, then accumulate over time so that the portfolio gets stronger. No one is forcing them to invest now or later, it is their own decision and they are responsible for their decisions.
