It's never too late to buy Bitcoin if we're talking about long-term storage. Investing in Bitcoin is just as good as buying gold or real estate, for example. You’re very lucky to have discovered such an opportunity and ended up with such a profit. Still, my opinion is that it's never too late to invest in Bitcoin – study the market, look into strategies like DCA, and you can start gradually if you have the desire and means. But remember, you're responsible for your own finances and investments, and it's always important to calculate all the risks in advance.
Buy at 96,000, hoping for 108,000 again? You can still buy $100 of BTC. But don't cry when BTC doesn't go to $350,000 in 2025.
They could take some portions and still continue with their investment journey, anyways those who would cry are investors who think short-term, those who are not disciplined enough to wait patiently and continue investing to maximize profits till their portfolio is due.
