It turned out that there's a big bounce upwards before hitting 9000. I would prefer stop loss right now for the reasons that:
- The big band of Bollinger Band gets to its narrow part. The price might get stuck there for a while.
- The general market is still bullish. Personally I believe it will go up back to 12000 or 13000 in a few days. Before confirming the trend that it's still bearish, playing safe is a good strategy.
