Both of this the most effective approach for me to reduce fear in my mind, my mind is already trained to understand that trading isn't always about winning and I always expect that I could lose then I combine that mindset with good budget management to minimize my losses if my strategy doesn't work out.
Sometimes we're afraid because we don't want to lose money and we're too focused on the results rather than the process. hHving some fear can actually be beneficial because it makes us trade more carefully instead of rushing to open position due to FOMO.
Fear can also save us from making bad trades when we decide not to open a position because the current market situation makes us uncomfortable. It's normal to feel that way but as long as we keep trading we can gradually learn to control our fear.
Fear will make you freeze and make bad mistakes, and that is what whatever works for you to lower your fear, that is the right path forward. If you have 1-5 and you make sure your fear is lowered thanks to these, then you are doing the right thing. For me, it has always been "use money you are willing to lose" because that means, even if all of it is gone, then I am going to be fine, and my life won't change. That is what it means to be fine when losing, doesn't mean you should not be upset.
You can be upset, but will your life change? I have seen people who are accountants at a firm and use the entire payroll of the company to invest in crypto, so they could sell and make a large profit and lose it all. So yeah, THAT changes your life. What I mean is, you wake up and go to bed the same way as yesterday, and nothing changes; you can be sad, but that's it. If you do that, if you invest with that kind of money, if you trade with it and lose, then you should be fine.
