There are hundreds of cryptocurrency exchanges you can use to buy crypto Fees can be based on price volatility, and many are charged per. Each one of these bear markets came after a spike in bitcoin's “cost per transaction.” Cost per transaction spiked late last year, according to. In fact, it has become very expensive and slow to conduct transactions using cryptocurrencies. It takes about 10 minutes for a bitcoin.

Investors have swarmed to this digital gold rush, often with little knowledge and a lot of hope. But there are numerous differences between stocks and cryptocurrencies. A stock is a fractional ownership interest in a business.

As a legal ownership stake in the business, the stock gives shareholders a claim on the assets and cash flow of the business. These back your investment and provide a basis for its valuation. Why stocks rise and fall: A stock price moves as investors assess the future success of the company.

That is, a stock rises in the long term due to the success of the underlying company. For a stock to be a successful investment, the underlying company must perform well over time. A cryptocurrency may allow you to perform certain functions, such as sending money to another person or using smart contracts that automatically execute after specific conditions are met. Why cryptocurrency rises and falls: Because cryptocurrency is not backed by assets or cash flow, the only thing moving crypto prices is speculation driven by sentiment.

As sentiment changes, prices shift — sometimes drastically. For a cryptocurrency to be a successful investment, you must get someone to buy it from you for more than you paid for it. That is, the market must be more optimistic about it than you are. Your time horizon — when you need the money from an investment — is a key criterion. The more volatile an asset, the less suited it is for those with a short timeline.

Generally, experts suggest investors in risky assets such as stocks need at least three years to ride out volatility. If you decide to take a stake in crypto, consider how it fits with your own risk tolerance and financial needs.

Second, there's no established common way to price bitcoin, which means nobody knows what it's "supposed" to cost, and the price is based purely on trading. Third, moving money across exchanges can be messy and inefficient, and requires lots of collateral to do efficiently. That means it's hard for traders to arbitrage differences across exchanges, which allows these price differences to persist for longer than they would in a more efficient market.

Finally, Pisani says there's an "infrastructure issue" wherein buyers can't currently quickly buy bitcoin across multiple exchanges at once, again, making it hard to arbitrage these price differences. Pisani says this will be something that needs to be looked into during the next year as bitcoin increases in popularity.

Most researchers analyze user sentiments related to cryptocurrencies on social media, e. Past studies have been limited to Bitcoin because the large amount of data that it provides eliminates the need to build a model to predict fluctuations in the price and number of transactions of diverse cryptocurrencies.

Therefore, this paper proposes a method to predict fluctuations in the price and number of transactions of cryptocurrencies. The proposed method analyzes user comments on online cryptocurrency communities, and conducts an association analysis between these comments and fluctuations in the price and number of transactions of cryptocurrencies to extract significant factors and formulate a prediction model.

The method is intended to predict fluctuations in cryptocurrencies based on the attributes of online communities. Online communities serve as forums where people share opinions regarding topics of common interest [ 13 — 17 ].

Therefore, such communities mirror the responses of many users to certain cryptocurrencies on a daily basis. Cryptocurrencies are largely traded online, where many users rely on information on the Web to make decisions about selling or buying them [ 4 , 18 ]. Moreover, the rise and fall in the number of transactions of Bitcoin and Ethereum can be predicted to some extent. For the proposed system, we crawled all comments and replies posted in online communities relevant to cryptocurrencies [ 19 — 21 ].

We then analyzed the data comments and replies and tagged the extent of positivity or negativity of each topic as well as that of each comment and reply. Following this, we tested the relation between the price and number of transactions of cryptocurrencies based on user comments and replies to select data comments and replies that showed significant relation. Finally, we created a prediction model via machine learning based on the selected data to predict fluctuations Fig 1. We crawled data needed to create the prediction model.

Once the environment for cryptocurrency trading among users is established, transactions between users lead to fluctuations in price [ 4 ]. We hypothesized that user comments in certain online cryptocurrency communities may affect fluctuations in their price and trading volume. Thus, we crawled the relevant data. Approximately types of cryptocurrencies existed as of February [ 22 ]. Of the available ones, we crawled online communities for the top three in terms of market cap, i.

We did not include Litecoin in this study because its online communities seemed not to be sufficiently active to be considered in this experiment, despite its large market cap and broad user base. Since Bitcoin was the first cryptocurrency, it has a large user community. In the Bitcoin community [ 19 ], data items were collected starting from December , when the cryptocurrency became widely available.

In the Ethereum community [ 20 ], data were collected from August 7, , since when the community stabilized to the extent that at least one topic has since been posted every day and transaction data are available. From the Ripple community [ 21 ], all data since the creation of the community were gathered.

In all communities of interest, we collected data in a legitimate manner, in compliance with their terms and conditions. Moroever, the collected data did not involve any personally identifiable information. The cryptocurrencies of interest in this paper had online communities where users shared opinions on the relevant topics.

The Bitcoin community [ 19 ] is divided into four sections, i. Each section has three-five subsections. For this paper, we crawled the discussion sub-sections for topics related to each of the cryptocurrencies. Comments and relevant replies posted by users on bulletin boards in each community were crawled. Furthermore, the time when each comment and replies to it were posted, the number of replies to each comment, and the number of views were crawled as well. Replies quoting previous comments and replies were crawled excluding overlapping sentences.

Based on the URLs of extracted topics, their contents and replies to them were extracted. The extracted topics, the dates on which they were posted, topic contents, reply contents, and reply dates were saved in. The Bitcoin and Ethereum forums were crawled on February 1 and 8, , respectively, whereas the Ripple forum was crawled on January 21, Table 1 outlines the arrangement of the opinion data that were gathered. The crawled data included garbage, e. Quite a few spam filtering techniques were investigated to remove such garbage data [ 15 , 24 — 29 ].

Any posting of more than two sentences found more than five times a day was considered spam and treated as such. Many past studies have dealt with classifying user sentiment or comment data [ 15 , 30 — 35 ]. In this vein, user reviews have been used to create a classifier based on machine learning [ 36 — 40 ], and user comments on the Web have been statistically analyzed for sentiment tagging [ 41 — 43 ].

Past research has mostly focused on classifying user comments in particular fields. Comments on online communities involve considerable use of neologisms, slang, and emoticons that transcend grammatical usage. Hutto and Eric Gilbert introduced an algorithm called VADER [ 44 ] to parse such expressions, and proposed a method to analyze social media texts by drawing on a rule-based model.

Online communities of interest in this paper paralleled social media texts. Thus, user comment data were tagged based on this algorithm. VADER normalizes positive and negative sentiments from -1 to 1. In this paper, each of the comments and replies was tagged see the opinion analysis example in Table 2. The crawled user comment data were tagged to create a prediction model. To create the prediction model, data selection was performed again. All opinions from very negative to very positive comments and replies could have been used.

Yet, we intended to improve the qualitative results and minimize operation cost. For data selection, we performed an association analysis between the results of opinion analysis and fluctuations in cryptocurrency prices. In this paper, the Granger causality test, which is widely used in research on the value of shares and currencies, was adopted [ 45 ].

As shown in Eq 1 , the results of opinion analysis based on the topics and replies VADER-based tagged values , the number of topics posted, the number of replies posted, and the number of views of the entire topics posted on a certain day were transformed into z-scores for standardization against the previous 10 days. Likewise, the fluctuations in the price and number of transactions of cryptocurrencies were transformed into z-scores for standardization against the previous 10 days.

Fig 2 shows an example of test results comparing the fluctuations in cryptocurrency prices and results of opinion analysis z-scores. Some opinions show a trend similar to that of fluctuations in cryptocurrency prices. The standardized z-scores underwent the Granger causality test to determine the significance of association. The Granger causality test relies on the assumption that if a variable X causes Y, then changes in X will systematically occur before changes in Y [ 46 ].

As demonstrated in previous studies, lagged values of X exhibit a statistically significant correlation with Y [ 15 , 46 ]. Correlation does not prove causation, however. We are not testing actual causation, but only whether the time series of a community of opinions contained predictive information regarding the fluctuations in cryptocurrency prices.

Our time series for the prices of cryptocurrencies and number of transactions, denoted by S t , reflected daily changes in the prices of cryptocurrencies and the number of transactions. To test whether the community opinions in the time series can predict changes in the fluctuations in cryptocurrency prices, we compared the variance explained by two linear models, as shown in Eqs 2 and 3.

The first model uses only n lagged values of S t i. We performed the Granger causality test according to models in Eqs 2 and 3. Based on the results of the Granger causality test, we can reject the null hypothesis, whereby the community opinions time series does not predict fluctuations in cryptocurrency prices—i. The Granger causality test was performed on each currency for a time lag of 1 to 13 days.

Experimentally, a time lag of 14 days and longer proved insignificant. Depending on the difference in each time lag measurement, elements showing significant associations were identified. For the prediction, the fluctuations in cryptocurrency prices were determined in a binary manner. We generated and validated the prediction model based on averaged one-dependence estimators AODE [ 47 ]. In the next section, we discuss the results of the applied system. Using our model, we made predictions regarding three cryptocurrencies Bitcoin, Ethereum, and Ripple.

Information concerning the price and number of transactions of Bitcoin was crawled via Coindesk [ 19 ], whereas price information for Ethereum was crawled via CoinMarketCap [ 22 ] and its transaction information was crawled via Etherscan [ 48 ].

Information regarding price for Ripple was crawled via rippleCharts [ 49 ], whereas its transaction information was not crawled. All data collected were in the public domain and excluded personal information. Table 3 outlines the arrangement of the market data that were gathered. The elements that exhibited significant associations in modeling for predictions were used for learning Tables 4 — 8.

P-values in the table are only shown for elements with prices of 0. An example of applicable input data is shown in Table 9. The results of the predicted fluctuations in the price and number of transactions of each cryptocurrency are discussed below. The accuracy rate, the F-measure and the Matthews correlation coefficient MCC were used to evaluate the performance of the proposed models.

These parameters are defined in Eqs 5 , 6 , 7 and 8 : 5 6 7 8. The prediction result proved to be the highest when the time lag was six days with an accuracy of Moreover, fluctuations in the number of transactions proved to be significantly associated with the section where a number of daily topics, very positive comments, and very positive replies were found.

The predicted result of fluctuating numbers of transactions proved to be highest when the time lag was three days with an accuracy of A fold cross-validation was performed on Ethereum for the entire days for days. A significant association with a number of positive user replies was also found. The predicted result proved to be highest when the time lag was six days with an accuracy of The predicted fluctuation in the number of transactions when the time lag was one day yielded an accuracy of Finally, Ripple underwent fold cross-validation for the entire days for days.

The predicted fluctuation in the price of Ripple proved to be highest when the time lag was seven days with an accuracy of Like Ethereum, Ripple proved to be significantly associated with very negative comments, and with negative replies when the time lag was seven days and longer. The prediction of fluctuation in the number of transactions of Ripple could not be performed due to difficulties in acquiring relevant data. To determine the effectiveness of the proposed prediction model, we performed a simulated investment in Bitcoin, using the simulated investment technique generally used in past studies on stock price prediction [ 50 ].

We invested in Bitcoin when the model predicted the price would rise the following day, and did not invest when the price was expected to drop the following day according to the model. The six-day time lag, which corresponded to the best result in this study, was used in the prediction model. The prediction model was created based on data for the period from December 1, to November 10, The day or week data for the period from November 11, to February 2, were used in the experiment.

Fig 3 shows the results of the simulated investment program based on the above conditions. The random investment average refers to the mean of 10 simulated investments based on the random Bitcoin price prediction. Over 12 weeks, the Bitcoin price increased by In random investment, the amount of investment increased by approximately This paper analyzed user comments in online communities to predict the price and the number of transactions of cryptocurrencies.

The proposed method predicted fluctuations in the price of cryptocurrencies at low cost. In terms of the prediction rates for Bitcoin and other cryptocurrencies based on the limited resources in online communities, the proposed method paralleled previous studies designed for similar purposes [ 15 , 51 ]. Moreover, user comments and replies in online communities proved to affect the number of transactions among users.

The proposed method proved applicable to buying and selling cryptocurrencies, and shed light on aspects influencing user opinions. Furthermore, the simulated investment demonstrated that the proposed method is applicable to cryptocurrency trading. Based on the learning data at the time of higher prediction rates, the types of comments that most significantly influenced fluctuations in the price and the number of transactions of each cryptocurrency were identified.

Opinions affecting price fluctuations varied across cryptocurrencies. Positive user comments significantly affected price fluctuations of Bitcoin, whereas those of the other two currencies were significantly influenced by negative user comments and replies. Moreover, the association with the number of topics posted daily indicated that the variation in community activities could influence fluctuations in price.

Further, unlike the price of cryptocurrencies, the number of transactions proved to be significantly associated with user replies rather than comments posted. The predicted result was most precise in Bitcoin, which seems attributable to the amount of accumulated data and animated community activities The predicted result was least precise in Ripple, which had the smallest community regardless of its market size 3.

These findings suggest that the difference in community sizes may have direct effects on fluctuations in the price of cryptocurrencies. Improving the precision of prediction requires a few improvements. Despite the association analysis used to filter user comments and replies, more qualitative selection criteria are needed to build a prediction model. This paper focused on online communities to determine associations and predict fluctuations. Yet, as with past studies, using data on the Web [ 52 , 53 ], analyzing social network data [ 46 ], and referring to search volumes on Google [ 10 , 12 ] are conducive to more precise results.

Moreover, partly adopting the stock market prediction technique used in previous studies [ 54 ] might help increase precision rate. In this paper, we acquired information from users in online communities as a viable source for research on cryptocurrencies. In the same vein, the sentiments expressed by user comments and replies in online communities seem applicable to further analysis and understanding of cryptocurrencies. Moreover, the propensities of online community users may help understand the attributes of the relevant cryptocurrency.

In addition, the rich information in online communities can contribute to understanding cryptocurrencies from different perspectives. Cryptocurrencies are increasingly being used, and their usability has drawn attention from different perspectives [ 2 — 5 ]. Research on cryptocurrencies is insufficient, in that hardly any currency other than Bitcoin has been investigated. The proposed method of predicting fluctuations in the price and trading volume of cryptocurrencies based on user comments and replies in online communities is likely to increase the understanding and availability of cryptocurrencies if a range of improvements and applications are implemented.

Furthermore, different approaches to user comments and replies in online communities are expected to bring more significant results in diverse fields. Analyzed the data: YBK. Browse Subject Areas? Click through the PLOS taxonomy to find articles in your field.
