We still don't know if Feds will increase rate or not, as they are delaying things. This might suggest global economic slowdown and dollar weakness.
Every time when FIAT is in trouble bitcoin is gaining, the only problem is that bitcoin market is not reacting to this news.
Bitcoin market is whimsical, it sometimes react fast and sometimes late.
I wouldn't exaggerate with so many external factors influencing price of the Bitcoin that much. First, Bitcoin has many of its own problems, among them mass adoption, as the main challenge.
Therefore, the price of Bitcoin is exclusively driven by speculation at the moment. And, as such, it may or may not fit the fiat events. However, I wouldn't forcefully look for much coincidence there, because there is very little there, and it is very easy to get biased.
