Decoding the Crypto Mindset with NLP: Bitcoin, Reddit and FTX

The bubble that burst but didn’t empty

When financial bubbles burst, they typically burst. When the crypto exchange FTX collapsed last November, many crypto skeptics expected Bitcoin prices to fall to the purpose where they thought they rightly belonged: around zero. However, on the time of writing, Bitcoin is price greater than it was leading as much as the FTX implosion. So what can we make of all this?

An essential consideration is where crypto investors get their investment data from. Accordingly a 2021 study by the National Opinion Research Center (NORC). At the University of Chicago, crypto investors get 24% of their information from social media and just 2% from brokers and financial advisors. Trading platforms and crypto exchanges provide one other 25% and 26%, respectively.

So how does this reliance on social media influence crypto market behavior? To discover, we applied natural language processing (NLP) techniques to crypto-related comments in various forums or subreddits on the social media platform Reddit and examined how the resulting sentiment evaluation correlates with Bitcoin prices.

Background on the crypto market

The topic-specific discussion forums that Reddit users subscribe to are able to moving markets. For example, the Wallstreetbets subreddit triggered the GameStop short squeeze in 2021, demonstrating the large impact these channels can have on finance and investing. Given the ever present presence of crypto investors on social media, we expected the influence of those subreddits to be particularly pronounced. The hottest finance and crypto-related subreddits based on their total variety of subscribers are listed within the attached table. (Wallstreetbets has banned discussion of crypto and is subsequently not included in our evaluation.)

The name of every subreddit gives an idea of ​​its general focus, however the word clouds below, which correspond to our study period – November 4, 2022 to January 15, 2023 – provide a more detailed picture and canopy the lead-up to the FTX collapse on November 6 after we conducted our evaluation.

Subreddit Word Clouds, November 4, 2022 to January 15, 2023

From the a whole lot of hundreds of comments on these subreddits over the study period, we isolated those who implied crypto sentiment based on seed words that indicated a general reasonably than specific connection to cryptoassets. FTX, for instance, could betray a sentiment bias given the controversy surrounding it, which is why we’ve got ruled this out. Crypto, Bitcoin, Ethereum, Cryptocurrency, Cryptocurrencies, BTC and Blockchain, however, are more neutral and were subsequently among the many seed words that guided our evaluation, the outcomes of that are summarized within the table below.

Model methodology

We tested many open source NLP models before selecting an optimized model RoBERTa model developed by students on the National University of Singapore (NUS-ISS) to conduct our sentiment evaluation. The model was trained on 3.2 million comments from the StockTwits investment forum and was a natural alternative resulting from its similar domain and enormous training scope. RoBERTa is predicated on that groundbreaking BERT model Developed by Google’s Artificial Intelligence (AI) team in 2018. Through their ability to research context, BERT models have increased the precision of NLP tasks by applying attention mechanisms that determine how words relate to one another. These attention mechanisms are the identical constructing blocks utilized in other large language models comparable to OpenAI’s ChatGPT.

The RoBERTa model labeled each crypto-related Reddit comment as 0 or 1, meaning bearish and bullish, respectively, and generated a each day average as an indicator of sentiment. For example, a worth of 0.5 indicated equally bullish and bearish comments. Differences between the StockTwits and Reddit domains and the way in which users comment on them resulted in some inaccurate labeling; However, we consider this may not have a fabric impact on the outcomes as we’re more concerned with the impact of the FTX plunge on sentiment than absolutely the measure of sentiment surrounding cryptoassets.

Results

For a more holistic picture, we combined all non-crypto subreddits and plotted the five-day moving average of each day crypto sentiment across crypto and non-crypto subreddits in addition to Bitcoin price over the identical period. Below the primary graphic is the comment volume for every day.

The three time series share some similarities: each shows that crypto sentiment becomes more pessimistic across the FTX plunge and recovers not long after, with non-crypto subreddits lagging behind their crypto-specific counterparts. When the non-crypto subreddits are singled out, the connection looks a little bit more precarious.

Economic sentiment vs. crypto sentiment and Bitcoin closing price

Investing Sentiment vs. Crypto Sentiment and Bitcoin Closing Price

Stock market sentiment vs. crypto sentiment and Bitcoin closing price

personalfinance sentiment vs. crypto sentiment and Bitcoin closing price

Financial sentiment vs. crypto sentiment and Bitcoin closing price

Stock sentiment vs. crypto sentiment and Bitcoin closing price

There isn’t any clear sentiment trend within the “Economy,” “Finance,” and “Personal Finance” subreddits, while “Stock Market,” “Stocks,” and “Investing” all point to a strengthening uptrend every week or two before Bitcoin prices rise again .

The following correlation matrices, which describe the connection between each subreddit’s each day average sentiment and Bitcoin prices, tell much the identical story. For example, crypto sentiment at Economics has a -0.034 correlation with Bitcoin price, highlighted by the purple-bordered cell.

So how did each each day sentiment rating relate to future Bitcoin prices? To answer this query, we added three more data sets: one, two and three days forward and BTC-USD +1, +2, +3 respectively. The cryptocurrency had the very best correlation with the present BTC price (in red border), while the Bitcoin subreddit had a comparatively low correlation (in orange border), but increasing for future prices (in black border), possibly indicating a certain predictive power could be concluded from sentiment values.

The finance subreddit showed a negative correlation (outlined in green). Due to the forum’s deal with traditional financial topics comparable to finance-related careers, homework problems, and job applications, community members could also be more skeptical about Bitcoin’s underlying value, which could explain the connection. Of course, our crypto seed words weren’t particularly common, appearing on only 27 of the 73 days examined, which was the smallest sample size amongst all of our subreddits, so there is probably not enough data to attract firm conclusions.

Other subreddits showed low correlations with Bitcoin prices. StockMarket (outlined in yellow) had a rather lower correlation than CryptoCurrency for Bitcoin price on the identical day, but didn’t maintain the identical relationship with future prices. The cryptocurrency sentiment-Bitcoin correlations one, two, and three days into the longer term are similar in direction to those between the worth of Bitcoin and its future prices (outlined in white), and are consistent with the autocorrelation often observed in stocks.

Implications

While the sentiment data from the varied subreddits implies some correlation with Bitcoin prices, a more fine-tuned NLP model trained specifically on the Bitcoin subreddit and never StockTwits could add to the robustness of those results and otherwise assess the accuracy of the model . Despite these caveats, nonetheless, our evaluation raises some interesting questions on how social media forums can influence market performance. What’s particularly compelling is how quickly sentiment recovered after FTX’s collapse, expecting Bitcoin’s price to rise again.

Such findings have a wide range of implications not just for the longer term of crypto investing, but additionally for investing basically. As more people use social media forums to make their investment decisions, herd behavior and self-reinforcing groupthink are prone to turn into more common, leading investors to follow investment narratives which have little or no basis in fundamental value. And if nothing else, no matter your opinion on crypto, it is a recipe for more market volatility.
