New Sentiment Index Tracks Public Opinion on Bitcoin
Published on August 19, 2014 at 15:04 BST
CoinDesk is pleased to announce the launch of its new Bitcoin Sentiment Index (BSI), which goes live at 15:00 (BST) today.
The BSI is a measure not of the value buyers and sellers place on their bitcoin, but whether individuals feel the digital currency’s prospects are increasing or decreasing at any given moment.
Powered by data collected by Qriously, a startup that leverages mobile ad infrastructure to deliver questions to millions of people across the globe, the index provides a snapshot of the general attitude towards bitcoin at the time of questioning.
Qriously co-founder and CEO Christopher Kahler told CoinDesk:
“The motivation behind the Bitcoin Sentiment Index is to create a time-series tracking the popular sentiment towards bitcoin, in particular how important people think bitcoin will be in the future. A lot of the interest in bitcoin at present is based on assumptions of this data, so we think being able to track and quantify it will be valuable and revealing.”
In order to gauge public attitudes to bitcoin, Qriously reaches out to members of the public in the UK and US via its mobile polling service.
The firm asks randomly selected smartphone users one simple question:
“The importance of bitcoin in 12 months will: (Increase/Decrease/Stay the Same)”
In terms of numbers, 85 people are asked the question per day in the UK and 50 in the US.
Fifty responses per day is the minimum required to have statistically significant distributions of answers with a seven-day moving average, Kahler said.
Qriously then computes a relative ‘sentiment’ score by adding the percentage of positive results to 100 and subtracting the percentage of negative results to create an index value. Instead of daily values, a seven-day moving average is used.
The question itself is served in the place of a mobile advertisement unit on both iPhone and Android users, who are selected at random to reflect the average smartphone-using population (as a proxy for the general population).
While currently opinions are gauged from individuals in the UK and the US, CoinDesk hopes to expand the geographical range of the survey to other countries in the near future.
Voice of the people
CoinDesk already provides the Bitcoin Price Index, an up-to-the-minute average price for the digital currency based on data from carefully selected major global exchanges.
However, while following the price of bitcoin can be interesting, at times perplexing and sometimes profitable, looking at general attitudes to bitcoin should provide a different kind of insight into state of bitcoin, now and in the future.
“The popular opinion, as opposed to expert opinion, for bitcoin is interesting and its utility is intrinsically tied to widespread adoption,” said Kahler.

The sentiment index is something of an experiment for CoinDesk and we value any feedback our readers may have on its value and potential improvements. Please email comments to [email protected].
