So, what's the most important thing? Predicting the trend, which is essentially strategic positioning. Without this big picture, all the so-called tactics are just rootless floating weeds. Take this drop as an example: $BTC happened to fall to its support level; $ETH broke through its support zone and is searching for a new support level below; $DOGE only dropped to the upper edge of its support level. These are all surface-level phenomena. It's hard to define things on an individual basis. Only when the big direction is set can you confidently move forward and embrace the rainbow.
