The results showed that there was a significant association between Bitcoin’s upcoming price and the volume of tweets during a day. Similarly, the volume of Google searches for the term “bitcoin” affect the Bitcoin price (Matta et al. 2015b). Some studies obtained similar results using wavelets (Kristoufek 2015; Vidal 2014). Ciaian et al. studied the price formation of Bitcoin using both traditional and digital specific factors affecting currencies. They found that market forces and Bitcoin attractiveness are two major factors in determining the Bitcoin price. Bouri et al. studied the relationship between Bitcoin and commodities, focusing on the energy market.

Over the years, it has hit many highs and lows, To better understand the past of this cryptocurrency, as well as its potential in the future, take a deeper delve into its history. Mining Bitcoins can be very profitable for miners, depending on the current hash rate and the price of Bitcoin. As of mid-September 2021, the Bitcoin mining reward is capped to 6.25 BTC after the 2020 halving, which is roughly $299,200 in Bitcoin price today. The live Bitcoin price today is $58,373.76 USD with a 24-hour trading volume of $34,593,589,257 USD. The current CoinMarketCap ranking is #1, with a live market cap of $1,102,112,567,063 USD. But a University of Cambridge study last year estimated that on average, 39% of “proof-of-work” crypto mining was powered by renewable energy, primarily hydroelectric energy. However, Musk reversed course in just a short time, saying last week that Tesla would stop accepting bitcoin because of the potential environmental damage that can result from bitcoin mining. The announcement sent bitcoin falling below $50,000 and set the tone for the big pullback in most cryptocurrencies. Bitcoins have to be stored in a digital wallet, either online through an exchange like Coinbase, or offline on a hard drive using specialized software.

This kind of fork requires only a majority of the miners upgrading to enforce the new rules. A hard fork is a protocol upgrade that is not backward compatible. This means every node needs to upgrade before the new blockchain with the hard fork activates and rejects any blocks or transactions from the old blockchain. The old blockchain will continue to exist and will continue to accept transactions, although it may be incompatible with other newer Bitcoin clients. The most popular wallets for cryptocurrency include both hot and cold wallets. Hot wallets are able to be connected to the web, while cold wallets are used for keeping large amounts of coins outside of the internet.

Gary Gensler, who took over as chairman of the Securities and Exchange Commission last month, has said that cryptocurrency markets would benefit from more oversight to protect investors. Earlier this month, the Federal Reserve said a survey of market contacts found roughly one in five cited cryptocurrencies as a potential shock to the system over the next 12 to 18 months. That’s a turnaround from the fall, when a similar survey found none mentioning cryptocurrencies. Even with the recent sell-off, digital currencies have a market value of about $1.5 trillion, according to the website coinmarketcap.com. But that pales compared with the $46.9 trillion stock market, $41.3 trillion residential real estate market and nearly $21 trillion Treasury market at the start of the year. Tracking bitcoin’s price is obviously easier than trying to figure out its value, which is why so many institutions, experts and traders are skeptical about it and cryptocurrency in general. Digital currencies were seen as replacements for paper money, but that hasn’t happened so far. Bitcoin has become popular enough that more than 300,000 transactions typically occur in an average day, according to bitcoin wallet site blockchain.info. Musk announced in February that his electric car company Tesla had invested $1.5 billion in bitcoin.

Stock market prediction is difficult due to its volatile and changeable nature (Kou et al. 2014; Kou et al. 2019); however, it has been extensively investigated by researchers. For example, Adebiyi et al. used a neural network to predict stock prices. Alrasheedi and Alghamdi used a linear discriminant and logit model to predict the SABIC price index, and Sathe et al. investigated share market prediction. More details can be found in other works, such as Cocianu and Grigoryan and Ma et al. . The results indicate that Bitcoin’s price forecasting in 5-days time window can be achieved with GM with average error of 1.14%. To the best of our knowledge, this amount of error is clearly less than previously existed results which have been cited in this article. The autocorrelation plot for 5-days prediction errors is depicted in Fig.3 which shows that the residuals are uncorrelated in time.
The very first major jump in Bitcoin price took place in July 2010. At this point, the value of Bitcoin went from about $0.0008 all the way up to $0.08, a truly dramatic increase in price. At this point and in the following year, very few exchanges supported trading of Bitcoin. There was also extremely limited liquidity at this time due to cryptocurrency still being relatively unknown. That meant that when the price started an increase in June 2011 from about $0.95, the approach was among the steepest recorded.

• The Winklevoss twins emphasized that they will not sell their bitcoins even if the price surpasses $380,000 dollars.
• It remained stable over the summer before spiking in November up to $460.
• If he thinks the “herd” is coming, as it were, then we all best pay attention.
• In other words, it provides for ownership rights as a physical asset or as a unit of account.

Since the grey system theory can make predictions with a small number of data and incomplete information, we used this method to predict Bitcoin price in next future day. The GM model is a grey prediction model in which n denotes the degree of differential equation used in the model and m denotes the number of variables. The key reasons for researchers using the GM model is the simplicity of its modeling, the implementation of the model, and the low need for time data. In this system, four observation points are needed to check for uncertain data and to reduce the error rate . That crash was made up for by a rally in October and November of that year. By early October, Bitcoin was at about $100, and it hit $195 by the end of the month. In November alone, Bitcoin had an unbelievable rally, going from $200 to more than $1,120. The causes of this rally were fairly obvious to most people, as more miners and exchanges were supporting Bitcoin. As the first cryptocurrency, Bitcoin’s long price history should come as no surprise. Bitcoin was created in 2009 by Satoshi Nakamoto, an alias for a person or group who has still not been revealed.

Why Is The Price Of Bitcoin And Other Cryptocurrencies Falling?

When he explained that bitcoin could reach that price ($10,000), the cryptocurrency was traded just at $413 dollars. The cryptocurrency expert and venture capitalist, Tim Draper, has also given its opinion about the future price of Bitcoin. According to him bitcoin and blockchain technology are one of the best things that happened for businesses. Going much more long-term, Novogratz said it was within the realm of possibility that the bitcoin market cap could one day reach the current market cap of gold, which is around a whopping $8 trillion USD. Last year everyone was going bonkers for Bitcoin, and that’s no surprise, seeing as how the number one cryptocurrency had an absolutely explosive price performance in 2017. Things have cooled off in 2018 as prices fell significantly, however many are still bullish about Bitcoin’s long-term potential. A hard fork is a radical change to the protocol that makes previously invalid blocks/transactions valid, and therefore requires all users to upgrade. For example, if users A and B are disagreeing on whether an incoming transaction is valid, a hard fork could make the transaction valid to users A and B, but not to user C.

Bitcoin is secured with the SHA-256 algorithm, which belongs to the SHA-2 family of hashing algorithms, which is also used by its fork Bitcoin Cash , as well as several other cryptocurrencies. Bitcoin’s most unique advantage comes from the fact that it was the very first cryptocurrency to appear on the market. Some concepts for a similar type of a decentralized electronic currency precede BTC, but Bitcoin holds the distinction of being the first-ever cryptocurrency to come into actual use. The very first transaction involving Bitcoin occurred between an early adopter and Nakamoto in January 2009. The first transaction in the real world is the notorious instance when a Bitcoin miner chose to buy pizza from Papa John’s. He famously spent 10,000 Bitcoins to buy two pizzas in 2010 in Florida. That transaction alone perfectly shows the dramatic change in value that Bitcoin has experienced over the years.

According to Coinbase, there are about 18.7 million bitcoins in circulation and only 21 million will ever exist. The reason for that is unclear, and where all the bitcoins are is anyone’s guess. Unfortunately, these new highs for Bitcoin were so far from the past figures that the price was very volatile. The volatility was fueled by rumors of poor security on Mt. Gox exchange, which was part of about 70 percent of Bitcoin transactions of the time. This was likely a contributing factor in the drop of Bitcoin’s price from $1,230 on Dec. 4, 2013, to $750 by Dec. 7. If the adoption trend continues, bitcoin could lead the market towards new all time highs. Additionally, payment processors are working with cryptocurrencies trying to spread their benefits. The co-founder of the cryptocurrency exchange Gemini, stated that bitcoin could be worth 40 times its current value. Mr Draper said in 2014 that Bitcoin could reach $10,000 in just three years, something that happened in 2017, exactly on the date he predicted.
A comparative study between a recurrent neural network and a vector autoregression was done by El-Abdelouarti Alouaret to predict the Bitcoin price. Their results show that RNN models have better performance than the VAR method. Recently, Jang and Lee compared the linear regression method , the support vector machine , and the Bayesian neural network for predicting Bitcoin price. They used 16 and 26 input variables to predict Bitcoin price for the next day and concluded that BNN is more accurate than both LRM and SVM.

This shows that a single five-day time window is robust and accurate for predicting Bitcoin price. Just two months later, on January 3, 2009, Nakamoto mined the first block on the Bitcoin network, known as the genesis block, thus launching the world’s first cryptocurrency. Bitcoin price was $0 when first introduced, and most Bitcoins were obtained via mining, which only required moderately powerful devices (e.g. PCs) and mining software. The first known Bitcoin commercial transaction occurred on May 22, 2010, when programmer Laszlo Hanyecz traded 10,000 Bitcoins for two pizzas.

Therefore, we compare the proposed method with RNN and BNN to show the accuracy and robustness of method proposed in this study. A comparison between the grey system theory and different neural network models is shown in Table10. The comparison confirms that the grey system theory outperforms both RNN and BNN. Table10 also shows that neural network models are sensitive to input variables. Previous works such as that of Chen et al. , Georgoula et al. , Kristoufek , and Matta et al. emphasize that the Bitcoin price depends on different inputs with complex behaviors. Based on new technologies, economic policies, and cultural behaviors, these inputs may change. Therefore, neural network models are not suitable or stable enough for predicting the Bitcoin price. The main advantage of the grey system theory is that it works well with small samples and poor informations. Therefore, the grey system theory is highly recommended for predicting the Bitcoin price.

The error percentages of the RNN, ARIMA, and LSTM models were 5.45%, 53.47%, and 6.87% respectively (James et al. 2013; McNally 2016). Greaves and Au investigated the characteristics of the blockchain network based on Bitcoin’s future price using an ANN. The results showed that the average accuracy is approximately 55%. Madan et al. used Bitcoin blockchain network properties to predict Bitcoin prices. Using SVM algorithms, binomial logistic regression classifiers, and random forests, they predicted the Bitcoin price with an accuracy of 55%. Georgoula et al. investigated the determinants of the Bitcoin rate along with an emotional analysis using SVM. The result showed that the amount of Wikipedia hits and hash rates in the network had a positive relationship with the Bitcoin price. In another study, Matta et al. aimed to predict Bitcoin trading volumes. They examined whether the general feeling that aggregates in a set of Twitter posts could be used to predict changes in the Bitcoin market.

January did see a high of over $17,500 around the 7th, but this was short-lived and followed by a steady drop. It rallied again, getting over $11,000 in early March, but this was followed by a drop back below $7,000. The largest recent high for Bitcoin was in early May, when it was above $9,500. Following a rise to more than $8,000 in late July, Bitcoin has remained around $6,000 to $6,500, other than a brief spike up over $7,300 in September. He has also said that due to the fact that bitcoin has a fixed supply, it is still a very underappreciated asset. Indeed, he stated that he and his brother believe that bitcoin disrupts gold. And Novogratz knows what “mainstream” and “institutional” looks like; he used to run a Goldman Sachs trading desk in Asia before becoming a hedge fund manager at Fortress. If he thinks the “herd” is coming, as it were, then we all best pay attention. To that end, the scarce, deflationary quality of Bitcoin makes it totally unlike traditional fiat currencies, which are usually prone to inflation and even hyperinflation in the worst of cases. That means as more investments pour into BTC, its price will likely continue to see upward pressure because there will be no supply response.

Bitcoin is currently the leading global provider of cryptocurrency. Cryptocurrency allows users to safely and anonymously use the Internet to perform digital currency transfers and storage. In recent years, the Bitcoin network has attracted investors, businesses, and corporations while facilitating services and product deals. Moreover, Bitcoin has made itself the dominant source of decentralized cryptocurrency. While considerable research has been done concerning Bitcoin network analysis, limited research has been conducted on predicting the Bitcoin price. The purpose of this study is to predict the price of Bitcoin and changes therein using the grey system theory.

Therefore, GM can be used to predict Bitcoin price and market trends which leads to reduce the risks of investing in cryptocurrencies. For the future work, one can consider some dependent factors in Bitcoin price and apply GM to predict Bitcoin price to get longer period prediction. Bitcoin is a digital currency that uses protocols and cryptographic algorithms to determine the security of transactions and to create new ones . Bitcoin is the first transfer and transaction system that uses nodes and that does not use third party processing and confirmation of transactions.
