The 20200$ level is critical for Bitcoin, which takes action by finding strength with the decline of the dollar index. If it stays above this level, bull expectations will start to increase. With the rejection from 21500$, if it holds above 20200$ again, it can create a buying opportunity. Although the interest rate hike by the FED next week is of great importance, a less-than-expected (0.70%) increase may be the beginning of an upward trend for Bitcoin.
