What is bitcoin?
Human behavior as they engaged in financial activities is intimately connected to the observed market dynamics.
Despite many existing theories and studies on the fundamental motivations of the behavior of humans in financial systems, there is still limited empirical deduction of the behavioral compositions of the financial agents from a detailed market analysis.
Blockchain technology has provided an avenue for the latter investigation with its voluminous data and its transparency of financial transactions. It has enabled us to perform empirical inference on the behavioral patterns of users in the market, which we explore in the bitcoin and ethereum cryptocurrency markets. In our study, we first determine various properties of the bitcoin and ethereum users by a temporal complex network analysis.
After which, we develop methodology by combining k -means clustering and Support Vector Machines to derive behavioral types of users in the two cryptocurrency markets. Interestingly, we found four distinct strategies that are common in both markets: optimists, pessimists, positive traders and negative traders. The composition of user behavior is remarkably different between the bitcoin and ethereum market during periods of local price fluctuations and large systemic events.
We observe that bitcoin ethereum users tend to take a short-term long-term view of the market during the local events. For the large systemic events, ethereum bitcoin users are found to consistently display a greater sense of pessimism optimism towards the future of the market.

Competing interests: The authors have declared that no competing interests exist. It is well-known that financial systems are complex and their evolution depends heavily on the behavior of their agents users. This realization can be traced back to the times of Adam Smith in the late s. Rational expectation assumes that people have access to all the information, act rationally, and adapt fast to new conditions.
Theories based on this behavioral assumption, however, are not able to model the real situation observed in markets although they give insights into key aspects of market behavior. It was soon realised that human behavior is more heterogeneous and complex than what efficient market theory has assumed. It spurred the invention of many agent-based models which simulate diverse users agents interacting according to a set of prescribed rules.
These models are able to explain many stylized facts in financial time series that previous models have failed to reproduce. Due to the sensitivity of financial data, there is little opportunity to construct behavioral models on the basis of empirical findings. However, researchers have found ways to gain experimental evidence by conducting laboratory studies [ 1 — 3 ].
The downside of the experimental approach is the limitation of sample size which prevents generalization of its findings to real financial market.
The invention of blockchain and cryptocurrencies has overcome this problem by opening up large data-sets of financial transactions for close examination. In addition, it has enabled researchers to study transaction networks, user activities, money flow, etc. There is, however, a dearth of research done on the ethereum network. Nonetheless, recent studies [ 7 , 8 ] have shown similarities of its network properties with that of bitcoin.
The study of user behavior in the cryptocurrency market has also mainly been conducted from the point of view of anomaly detection [ 9 — 11 ]. To the best of our knowledge, there are as yet no studies done on the behavioral structure of the users of cryptocurrency market.
An understanding on the behavioral structure of cryptocurrency users would allow us to answer questions such as which strategies would the users follow in the cryptocurrency market, and how different or similar they are from those adopted in the behavioral models of other financial markets.
The goal of our research is to first develop the methodology that would allow us to derive the type of strategy employed by the cryptocurrency users from the blockchain data. Next, we investigate into the behavioral structure of the cryptocurrency users and elucidate the number of different strategies exist in the real market. We aim to gain insights into the behavioral composition of these users in the two largest cryptocurrency systems in the market: bitcoin and ethereum.
We investigate into the composition of user behavior in response to events that happened at different periods of these cryptocurrency systems: local price fluctuations in bitcoin and ethereum; and shocks in the whole cryptocurrency system termed as Crypto Bubble and Crypto Winter. Our interest is to look at the persistent behavioral patterns rather than at the high-frequency strategy switches—the users might change their strategies every day, but we want to look at their overall attitude during these periods.
For this purpose, we construct temporal transaction networks of cryptocurrency at an interval of one month for both the bitcoin and ethereum systems, and examine the properties of the constructed networks. Then, we define the set of features that allow us to distinguish strategy types and ascertain their presence for all the nodes in our networks.
We implement various machine learning methods to find clusters of users with different behavioral patterns. Overall, it is possible to detect user strategies in cryptocurrency markets and we are able to define four distinct behavioral types universal for both the bitcoin and ethereum systems. The organization of our paper is as follows. In section 2, we provide an overview on the current state of research relating to the understanding of trading behavior in financial markets in general and in cryptocurrency markets in particular.
We then review research on the application of machine learning techniques to blockchain data. In section 3, we introduce our dataset and explain how we perform feature selection and extraction in our paper. In section 4, we describe our developed methodology for defining strategies from the data set.
In addition, we show the implementation of this methodology to extract behavioral patterns and discuss our obtained results. Finally, we conclude our paper and propose potential future directions for our research. There are plenty of research conducted on behavioral types in financial markets and various models have been proposed.
A thorough review of existing agent-based models has been done in the thesis of Feng [ 12 ] and the review of Iori [ 13 ], where they showed the evolution of agent-based modelling in finance. On the other hand, research on strategies and users behavior in cryptocurrency markets are few. Cocco [ 15 , 16 ] has proposed an agent-based model to explain price movements in bitcoin. They assumed that there are two types of behavior in the bitcoin system: chartists and random traders.
The authors then prescribed behavioral rules to the agents according to their type and observed how they affect the market price of bitcoin. As for experimental research to understand the behavior of users of the cryptocurrency system, interesting work has been done by Krafft [ 17 ].
These researchers have conducted online experiments to study how users are susceptible to peer influence in cryptocurrency markets. This study has shed light on the understanding of causal impact of individual opinion in large cryptocurrency markets.
The use of machine learning methods in blockchain and cryptocurrency data sets is not new and has already been implemented for various purposes.
The most popular task is to use machine learning to detect anomalous user behavior. The authors in [ 9 ] have analysed bitcoin transaction network data for the four years with the goal of detecting suspicious users. They used Local Outlier Factor LOF to first detect outliers in the dataset, and then employed k-means clustering to calculate the relative distances between the cluster centroids and the detected outliers.
Overall, the authors were able to detect anomalous transactions using this approach. Another study on the detection of anomalous user behavior has been conducted by Monamo [ 10 ]. They used trimmed k-means clustering to detect outliers, i. In [ 11 ], the authors trained a supervised machine learning algorithm to predict the category of the unidentified users.
Identified users a sample of of the million transactions were used as a training set for the Gradient Boosting algorithm, and classifiers were built to differentiate users among 12 categories—exchange, mining pool, personal wallet, scam, darknet, ransomware, hosted wallet, gambling, mixing, stolen coins, merchant services and others.
Overall, the detection of user types in cryptocurrency systems is mainly to address the security and privacy issues. Furthermore, most of recent research focuses on the bitcoin transaction network, with less work being performed to understand the cryptocurrency system as a whole [ 18 ]. These approaches have been successfully applied to cryptocurrency markets as well [ 15 , 16 ]. However, there is still a lack of studies that derive users behavior in financial markets from empirical evidences.
The successful implementation of machine learning methods in identifying anomalies and user categories has inspired us to employ them for the identification of behavioral patterns in cryptocurrency system which would contribute to the understanding of human behavior in financial markets.
Bitcoin transaction data was extracted from the full Bitcoin blockchain starting from the genesis block dated 3 January up to block , dated 25 January Based on the processed data [ 22 ], the temporal network of interactions of bitcoin users was estimated.
Since the clustering algorithm is heuristics-based, it does not guarantee that all the wallets in the network are clustered to corresponding users. Therefore, we might expect a certain fraction of non- or poorly clustered wallets, but still this algorithm results in a significant improvement of network representation of financial interactions in bitcoin.
Example of the bitcoin dataset is demontrated in Table 1 :. In our research, we have used the processed ethereum dataset from [ 23 ] and example is shown in the Table 2.
Our interest is to elucidate the behavioral composition of the users at different periods of the bitcoin and ethereum systems. For this, we first define periods of distinct price behavior, i. To define the trend of price movement, the average relative daily return and the total relative return in one month for both cryptocurrencies are calculated. Table 3 shows the chosen periods with the return values. Next, we analyze user composition in both bitcoin and ethereum during the occurrence of extreme events that affect the entire cryptocurrency system: a December —January aka Crypto Bubble , b the period after this event, and c the shock event at the end of known as Crypto Winter.
We construct a temporal, weighted, and directed network for each of the defined periods where each link i , j , w , t is a transaction between two nodes users i and j at time t with the amount of coins w. The main properties of each network are shown in Table 4. From the constructed networks, we calculate properties features of each user. Our goal is to yield the various strategies employed in the cryptocurrency market.
According to the literature [ 12 — 14 ], agents in the financial markets tend to adopt one of the following strategies: buy, sell, trade or hold. Based on the constructed networks with properties shown in Table 4 , it is possible to obtain the required information. The following are features that we shall use to define the type of strategy employed in the cryptocurrency market:. Due to the novel nature of cryptocurrencies, there are many users both in bitcoin and ethereum that are experimenting with system by placing random orders and leaving the system quickly.
We consider these users as noise and omit them from the analysis, since they do not contribute to the overall understanding of market behavioral structure. Moreover, they cause confusion to our analysis by the machine learning algorithms as we try to define the existing behavioural pattern in the market. Then features are calculated for all users under analysis in each network see Table 4. In [ 4 , 5 ] it has been shown that degree and wealth in the bitcoin network are power-law distributed with the exponent around 2.
We found that indeed, in, out and total degree are power-law distributed with the exponent around Heavy tailed degree and wealth distributions in various financial markets is well-known fact and has been extensively researched [ 24 — 27 ]. Cryptocurrency market also shows this property similar to other markets. We then select features for the machine learning model from those listed above.
Overall, unsupervised feature selection methods can be categorized as filter and wrapper approaches [ 28 ]. Filter approach selects the most relevant features based on certain criteria correlation, entropy etc. In our research we first calculate correlation between various features, then define a few set of features for further analysis. The final choice of the most optimal feature set will be based on the clustering result.

Financial Innovation volume 5 , Article number: 2 Cite this article. Metrics details. In the context of the debate on the role of cryptocurrencies in the economy as well as their dynamics and forecasting, this brief study analyzes the predictability of Bitcoin volume and returns using Google search values. We employed a rich set of established empirical approaches, including a VAR framework, a copulas approach, and non-parametric drawings, to capture a dependence structure. Using a weekly dataset from to , our key results suggest that the frequency of Google searches leads to positive returns and a surge in Bitcoin trading volume. Shocks to search values have a positive effect, which persisted for at least a week. It is difficult to make a prediction, particularly about the future!
