Three years ago, I turned 10k USD into 670k USD.

I didn't rely on insider information, nor did I catch the crazy bull market; I just used a set of "simple methods"—treating trading like leveling up in a game, gradually grinding my way through. $RONIN
During these 1095 days, I summarized six key insights. Understanding one can help you lose fewer tens of thousands; mastering three can help you outpace most retail investors.
1. Rapid rise and slow decline is the main force's strategy to accumulate shares and shake out weak hands. After a quick surge, a slow pullback is not a sign of collapse but a routine operation by the main force to clear out floating shares and shake out indecisive retail investors. True top signals are often characterized by a volume spike followed by a sudden waterfall sell-off, trapping retail investors into holding the bag.
2. Rapid decline and slow recovery indicate the main force secretly unloading. After a flash crash, a slight bottoming and rebound may seem like a good buying opportunity, but in reality, it's the final trap to lure more buyers. Never be misled by the oversold illusion; this is the moment when retail investors are most likely to get caught in a deep trap and suffer a reversal.
3. Continued volume at high levels indicates ongoing momentum; no volume means a pullback. Persistent volume at high levels suggests active capital battles and potential for further upward movement; once volume diminishes and the price consolidates sideways, it indicates a lack of capital support and is a precursor to a sharp decline.
4. A single large volume spike at the bottom does not mean a bottoming; sustained volume increases signal genuine accumulation. A single bullish volume candle is often a trap to lure more buyers; only after thorough shakeouts and multiple days of sustained volume can it be considered a real sign of the main force building a position.
