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

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

3, I personally lean towards the view that there's still more upside to go. When it pulls back to a small-level support and stalls, I'll prepare to close out my short positions first - there's no momentum left.
