It actually depends on your preference, your situation in life, your age, your marital status, and other things that may or may not make you more comfortable in a particular strategy.
There's also the timing, luck, and which part of the cycle Bitcoin is currently in. I admit that I merely got lucky with the timing in 2019. I had the savings, and I had NO responsibilities/distractions.
Though it's quite cool if you can get Bitcoin at a cheaper rate, but timing the market before making a purchase is what am not a big fan of, because the possibilities are high that you might just be wasting your time in your accumulation journey.
Additionally, you might encounter a very good price to buy, which might be a dip, but greed of wanting more might set in, am you may not buy them, hoping that it's going to drop even further, which might makes you miss that buying opportunity, so it's because of these i just don't feel ok timing the market because that's what traders do, not investors like us
It is impossible to determine the price of Bitcoin, whether the price of Bitcoin will be good for you at the present time or not depends on you. If you have full confidence in Bitcoin and believe that the future of Bitcoin is bright, then you will be interested in investing in Bitcoin. If you consider the history of Bitcoin, you will understand that Bitcoin has increased in value more than we feared. If you wait for a fall to invest in Bitcoin, then this is a bad habit and you will continue to increase this bad habit, so get out of the bad habit. However, for you, investing in the DCA method will allow you to continue investing for a long time. On the other hand, you can invest without paying attention to the market because then your goal will be to invest in Bitcoin and do it for the long term.
