There is still plenty of time and ways to collect Bitcoin. Using the DCA method is one way to collect Bitcoin. Buying Bitcoin when the bearish season occurs is indeed the right choice. But we have to know that for now the bearish season will likely never come again because we see Every week Cryptocurrency prices always increase in price.
Now I am asking myself whether you know that there will be a bearish season in the context of where we are now? It's like an empty statement, it is like
buy low sell high. Of course by low sell high, problem is nobody knows when it will be low and when it will be high. And when it feels high, whether it is high compared to what potential is still in the air.
Same thing for your second part of the post. I am sure that for most people going up or down is a coin flip. Or maybe some of them are these hyper naive people thinking that bitcoin can only go up. Risk is still there and the fact that bitcoin is so extremely multifaceted means that on the one hand it makes bitcoin resilient, but on the other hand it might be susceptible to government attacks in the form of unfavorable legislation, for instance.
I have recently heard Trump say that he hates Biden's stance on bitcoin and Musk is one candidate he wants to get on board to counsel him on the topic. Whatever you think about Trump or Musk, it shows that there are things nobody has yet an influence on or knows what's going to happen once he would become the next president. Who knows, maybe he decides to be extremely pro bitcoin and passes laws nobody would have expected. That could boost bitcoin out of nowhere.
The one part that is true is that there is plenty of time to acquire more BTC. There are various ways of doing so, depending on what someone does for a living, for instance. Buying BTC is one way.
