What are analysts saying?

With bitcoin now down by more than 15% from its early May high, when it traded near the $10,000 psychological level, one analyst thinks the market suffered from over-exuberance. Throughout the year, each time market participants have expected growth, the trend has reversed into a decline, wrote Alexander Kuptsikevich, analyst at FxPro.

Bitcoin in particular, after having experienced growth for 3 weeks and attempted to move above $10,000, is now in a downward trend that has already lasted for two weeks.
