your investment strategy seems to be the same as mine, simple day trading strategy. for me there is no strategy that is too grandiose that I will do but only based on the experience I gain from what I have done and I continue to try and improve if there are mistakes, because then I can better understand what we are going to do.
but I also don't close myself off from a strategy that many of my colleagues on the forum look like and don't hesitate to adopt as long as it's in accordance with what strategy I'm going to do and is also profitable. no strategy is more reliable than doing it yourself, but not rejecting the fit of others.
I agree that nobody should be doing something that is too difficult for them, not just in the sense that it will not be profitable, but in the sense that we should not be really looking into something that we do not feel comfortable with. For example, scalping is something I am not comfortable doing, and I end up trying it a bit to see how it feels and I didn't feel good at all, same goes with high leverage trading as well, all those people who do 100x or even as high as 150x are just crazy in my opinion, but some people make it work, I can never do that.
For me, it is all about DCA and long term investment, as long as I can invest in the long term profits then I am fine, I do about 2-3 years long investments in some small cap coins and I do even longer for bitcoin which is hopefully over a decade long, that feels a lot better for me personally.
