I was under the impression that Yellen was hawkish, but guess she's taking a page out of Bernanke's book.
Gold and other precious metals have made pretty large moves following FOMC minutes, so not really surprised there but I am going to be watching how /GC trades in the upcoming days.
As far as Bitcoin is concerned, it is still relatively new, so it's natural that people are slow to adopt and price volatility being high is to be expected. This past crypto rally, however, has probably been the strongest yet in my opinion.
Going to be closely watching BTC and other cryptos after BIP 148 goes into effect on August 1st.
