In its relatively short lifespan, bitcoin has been subject to dramatic rallies and jaw-dropping declines. Various factors have been at play during bitcoin’s big price moves, but some market observers have speculated that herd mentality has contributed to those significant price moves in both directions.

A new survey from DataTrek Research confirms that sentiment.

“According to a recent survey, more than half (52%) of the respondents said they believe crowd psychology is the main driver of the price of the No. 1 digital currency,” reports MarketWatch.

Recent speculation about a bitcoin exchange traded fund finally coming to life can be seen as an example of mob mentality driving prices higher. As momentum (and speculation) for bitcoin ETF approval has increased in recent weeks, so has bitcoin’s price.

Bullish sentiment has been fueled by a spate of news from institutional investor interest from firms, such as BlackRock who is looking to assemble a working group to explore opportunities in cryptocurrencies and blockchain, their underlying technology. In addition, cryptocurrency ETFs from the likes of Bitwise, VanEck and SolidX are currently pending SEC approval–a move that could help give cryptocurrencies more approval from reticent investors.

“The holding and storing of digital currencies—was the biggest issue for investors, with around 38% saying a cryptocurrency would never become a global reserve asset. DataTrek surveyed 216 people of which 42% were in the traditional money management industry and 24% were brokers,” according to MarketWatch.
