1. Big Bitcoin's short-term support is around 72500. As long as this level doesn't break, it can continue to push higher and squeeze out short sellers, so bears shouldn't be too optimistic yet;

2. 70000 can be considered a medium-term watershed level;

3. I'm personally inclined to believe there's still more upside to play out. When it pulls back to a smaller support level and stalls, I'll be ready to close out my short positions first. There's no momentum left.
