Even though you are very good at doing TA and have deep knowledge about trading still was hard to timing the market price due to its volatility. That is why some holders wanted to stay as holders rather than use their funds to trade because they thought it was less risky and not stressful. Of course, if you are not really confident to do trading why you should do it in fact, we can still earn a profit from just holding and selling at high. It was not how we miximized our funds while waiting for the bull season but we chose the way that we thought it never gives us losses which holding does.
It is logical that everyone will act according to their beliefs, how they see the market. I chose long-term investing for myself because I know that for me it is the best possible option. If there is a trader who can earn more over the long term than Bitcoin can grow, then of course he will trade and eventually earn more than me, but this does not mean that this can change anything for me, because I am not such a good trader and often suffer losses because I am just learning. But if you look at the high-status users of this forum, almoust everyone says that hold btc defeats any other attempts to make a profit, so why try to invent something new?
I agree that it is best for me too. There are a lot of people who try to trade and make a profit but I personally believe that I would not be able to make as much profit from it that way as I possibly could and I rather not do that at all. This is why it is a lot better if we are smarter about it, and should be doing some good return in the end.
I get that it could be a bit more of a challenge in the end if we are not careful, but as long as we get to do what we want to do, we should be fine with it without a worry. Many people care about maximizing, and they do not really realize that they should be able to actually do something that would make more profit if they were careful about it. That is why long term is the way to go.
