I just have a small point that today bitcoin price is around $70k and if we are comparing last 7 years DCA till today then it looks good. But few months back price of Bitcoin was under $20k and at that spot thing might not look as ideal as they are today.
There is consent that some investment is better then zero investment. If I talk about myself then if I have been investing into bitcoin since 2017 then I might be in some good position. But since I started investment quite late so I have to wait for a while to see my portfolio in good position.
I think it is not a complicated problem for you to continue investing in Bitcoin and also for people who still want to invest in Bitcoin. Because from 2017 to this year it is almost seven years, in general you have seen a lot of things through the market, especially for the price of Bitcoin itself. But if you have spent just five years investing in Bitcoin, at this time your Bitcoin portfolio is also very good because you must have seen two ATHs that occurred in Bitcoin and there is still a possibility that it will happen again this year. So keep investing with whatever strategy you want without complaining about the current Bitcoin price.
