Playing 100x contracts, wanting high profits and high win rates, the key lies in the following points:

1. Fixed total position, never over-invest. When the market is good, you can make tens of thousands of USDT, but you can also bear losses without significant damage.

2. Start small, when opening a position, first test the waters, for example, only invest 10 USDT and observe the market reaction. If the direction is correct, then consider increasing the position to reduce risk.

3. Use profits to increase positions, only after making profits should you use the profits to add to your position, ensuring that even if the market fluctuates, your principal can be preserved.

4. Decisively cut losses, after making money, you must adjust the stop-loss level in a timely manner to ensure profits and avoid giving back profits.

Operational skills: Cap your funds at 300 USDT, start with small positions, only increase positions when the trend is clear and you have more than 70% confidence, and ensure to use profits for adding positions.

If the market moves against you, you can still preserve your principal. For example, if BTC is at 60,000, I take a short position of 10 USDT, with 100x leverage, waiting for a big market move. If it falls below 60,000 accompanied by negative news, then consider using the profits made to increase the position, while also setting a stop-loss.

Playing 100x contracts, high profits and high win rates, the key lies in fixed total positions, starting small, using profits to add positions, and decisively cutting losses, so that even with market fluctuations, you can preserve your principal.
