In the crypto world, **left-side trading** and **right-side trading** are two completely different trading strategies, with the core difference lying in the **timing of entry** and the logic of market trend judgment. Below is a detailed comparison of the two:

---

### **1. Left-side trading (counter-trend trading)**
- **Definition**: Positioning in advance when there is no clear trend reversal signal in the price, usually by buying in batches during a decline (or selling in batches during an increase), **counter to the current trend operation**.
- **Core Logic**:
- Believe that the market will "oversell" or "overbuy", and seize the reversal opportunity in advance.
- Rely on valuation, support/resistance levels, and technical indicators (such as RSI oversold/overbought) to determine bottoms or tops.
- **Typical Scenario**:
- Bitcoin has dropped 50% from its peak, and left-side traders may start to buy in batches, anticipating a rebound.
- Gradually build positions during the bear market and wait for the bull market to arrive.
- **Advantages**:
- Cost advantage: able to accumulate at a lower price (or sell at a higher price).
- Suitable for long-term investors or value investors.
- **Risk**:
- It's easy to "buy the dip halfway up"; you may continue to incur losses before the trend reverses.
- Need to bear significant psychological pressure (against human nature operation).

### **2. Right-side trading (trend trading)**
- **Definition**: Get on board after waiting for a clear confirmation of the trend, for example, following up after the price breaks above the previous high (or below the previous low), **operating in accordance with the current trend**.
- **Core Logic**:
- "The trend is your friend," only engage in markets with higher certainty.
- Rely on trend indicators (such as moving average golden cross/dead cross, MACD, volume breakout, etc.).
- **Typical scenario**:
- After Bitcoin breaks through its historical high, chasing the rise or confirming a rebound after a sharp drop to get on board.
- Increase positions after the bull market starts, stop losses after the bear market breaks.
- **Advantages**:
- Higher win rate, avoid counter-trend operations too early.
- Suitable for short-term or trend traders.
- **Risk**:
- The entry position may be poor (chasing highs or panic selling).
- Lagging: May miss out on some profits.

|----------------|---------------------------|---------------------------|
| **Timing Selection** | Counter-trend operation when the trend is not confirmed | Trend-following operation after the trend is confirmed |
| **Cost** | Lower cost (but may be trapped) | Higher cost (but stronger certainty) |
| **Risk** | High (Countertrend Risk) | Medium (Lagging or False Breakout Risk) |
| **Target Audience** | Long-term investors, value investors | Trend traders, short-term traders |
| **Psychological Difficulty** | High (need to counter market sentiment) | Low (follow market sentiment) |

### **crypto world application suggestions**
- **Left-side trading**: Suitable for investors with in-depth research on the project and ample funds (such as dollar-cost averaging Bitcoin), who need to strictly build positions in batches and set stop-losses.
- **Right-side trading**: Suitable for highly volatile altcoins or short-term trading, requiring quick responses and strict profit-taking and loss-cutting.

**Notice**: The crypto world is highly volatile, and two strategies can be used in combination (for example, establish a bottom position on the left side, then increase the position after confirming the trend on the right side).
