Compared to more traditional assets, bitcoin's bull and bear cycles can be difficult to forecast and explain. Bitcoin observers have speculated that recent price action has something to do with moves by China to crack down on illegal exchanges and to formalize the Chinese government's backing of blockchain technologies, as well as recent changes in how hard it is to create bitcoin. China plans to issue its own cryptocurrency, which could launch within the next 18 months.

Kazley noted that difficulty rallied to new heights in 2018, bringing bitcoin prices along with it. But bitcoin saw a "substantial difficulty decline" two weeks ago, according to Kazley. "Today, difficulty adjusted upwards slightly, but market participants are keenly watching to see if a bearish difficulty trends continue," Kazley said.

"However, we did see a steep difficulty decline in October 2018, which coincided with a very large selloff from the $6,000s to the $3,000s in about a month's time."
