Yeh pointed to the Scaling Bitcoin conference in Hong Kong, which produced the 'segregated witness' scaling solution that doesn't require a hard fork as one example. Additionally, the Satoshi 'unmasking' by Wired and Gizmodo has cast a spotlight on the cryptocurrency, he said.
Yeh said bitcoin may simply be rebounding from a pronounced price dive in 2014, when it was "very oversold". Conversely, he said the technical indicators, in his view, showed that bitcoin is now on a trajectory similar to its massive run-up in 2013, which led to it breaking the $1,000 mark

So dont think about 1000$,but 600$ is coming
