Actually i think there are 2 kind of people (in my opinion) that success in crypto. Of course these factors is not athe only why they are good at it.
So, some people are have a priority at "Looking at the strategy and know when to used it" and also a people that have priority about "Risk and Asset Management", both of these factors maybe related, but i just prefer on the second. Because the strategy is just like a gamble, no matter you use it or not. it will give the same result in the end.
