How to effectively review?
In fact, you just need to grasp a key point: backward reasoning.
That is, use the existing trend to infer the original intentions of the major players, and then compare it with your initial analysis when you decided to invest, to see where the deviation occurred?
How to understand?
For example, "volume contraction and price increase", you judged it to be the start of a cryptocurrency and decisively invested, but the subsequent trend went down all the way, then "volume contraction and price increase" was actually a means for the major players to lure in more investors.
When you initially judged it to be the start of a cryptocurrency, did you overlook the position of the cryptocurrency (high? low?)? Or did you not pay attention to the extent of the shrinking transaction volume (extreme? relative?)? Because only a volume contraction and price increase at a relatively low position can be highly likely judged as the start, while volume contraction and price increases at other positions should raise a question mark?
And so on.
Through constant review and reinforcement, when you encounter a similar trend again, a reflex will remind you: proceed with caution.
Over time, the pitfalls you have encountered will gradually become the cornerstone of your journey in the cryptocurrency world.
