Broadly speaking, someone who invests in bitcoin is certainly based on their belief in bitcoin itself, and I see things that don't make sense when they invest in bitcoin while they don't believe in it, I can say they depend on luck and roughly they can be said to be someone who is gambling.
I was the same, when I entered and invested in bitcoin based on my trust in bitcoin with all the benefits offered. And I believe in it.
DCA is one of the strategies that is widely recommended, and I personally apply this strategy, yes even with a small amount but it is based on my ability in finances that I have planned as well as possible to prevent and anticipate something that I don't want to feel in the future / DCA.
It will surprise you to know that many people joined Bitcoin for the hype of bull run and not because of their believe in Bitcoin. To them, they just want to make huge profits over little effort and short time and these are the people that bought at the peak and some of them end up in agony during time of dips; agony because they were not psychologically prepared to handle periods of dips and consolidations. It is usually a matter of time before they truly understand what they got into and from then forward some will take the time to study the trend, the tech behind Bitcoin and how best to approach the market while others will sell at loss and live to rue their actions. If you are active in social media, you would have seen some people narrating their ordeal with Bitcoin; how they lost money and all manner of fud.
Well, the longer one stays in Bitcoin, the calmer one gets because times somehow make us understand the possibilities, potential and the future in Bitcoin. So I always advice everyone to give it time.
I'm not surprised by that at all, because I also realize that many people are just taking advantage of the bullrun to make a "quick" profit without having to wait long. But are you sure they are just doing that without trust in bitcoin? I mean even if they do that kind of thing (buying on a bull run) they are just taking advantage of the right momentum for them to enter. I can say they don't have the mentality or don't want to wait for a long time to make a profit and they prefer the short path even though the profit may be smaller than those who buy from a bearish market situation.
Maybe here I can say that only strategies are different because among us must have different reasons.
