I totally agree with this but there are some cases you really need to act fast or you will be rekt, sometimes you better go out of a certain coin with -%5 better than stay and hold with -%90. Being patient is, of course, a good thing but the skills of acting fast is also a great thing and if you can choose between those correctly you will be perfect and we all know that no one is perfect everyone will make mistakes between those 2 decisions.
