my simple thought on simple patterns
1. big bear flag overrules the trend after the small downward wedge occured
2. Head n shoulders pattern
3. potential fibonacci time channel that could map H&S pattern
4. trend lines price range crosses fib time channel, price could drop to 10-20k USD at the end of H&S pattern.
not a finanical advice , it's from my very simple thought only :p
i might be wrong.
