Pls don't misunderstand, just an assumption: if Bitcoin were to reach $500 again today, do you think people would still be willing to buy?
In my opinion, it would have two implications. Firstly, it would likely have ruined many people's investments and life savings, considering those who bought in at $10k, $20k, or even $100k. 
Secondly, it would reinforce the skepticism of those who don't trust digital currencies due to their perceived unreliability. So, if it happens, would you still buy it? 
Ideal and experienced investors are never afraid to invest in Bitcoin, only weak hands are afraid to invest in Bitcoin and when the price is dumping in the Bitcoin market, they sell Bitcoin. I never believe that Bitcoin will reach $500 (and if it does, I will definitely buy Bitcoin and hold it for a long time). However, such an opportunity naturally arose in late 2022 and early 2023 when the price of Bitcoin touched $15k. 
Those who invested in Bitcoin at that time are the most self-sufficient at present, and those who were weak investors sold Bitcoin at that time and the owners of the Bitcoins they sold are regretting it now.
Those who are still holding Bitcoin since 2022 are currently making very good profits, and they will definitely be able to hold Bitcoin for another 10 years in the future, because if they can truly understand the 3-year Bitcoin movement from 2022 to the present, then they will definitely be able to believe in the future possibilities of Bitcoin, because they are now mentally stronger and more mature. And because of this, they will be able to keep their investment for a much longer period.
But, those who sold their Bitcoin at that time, And deprived of current success and now just regretting for it, they should not look at the past, just think about the future possibilities and try to fully utilize the opportunities for future profits. Bitcoin will continue to be valuable over time, but the longer you delay investing in Bitcoin, the more you will fall behindof getting success.
