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.

At Bitcoin price today in mid-September 2021, those pizzas would be worth an astonishing $478 million. This event is now known as “Bitcoin Pizza Day.” In July 2010, Bitcoin first started trading, with the Bitcoin price ranging from $0.0008 to $0.08 at that time. Bitcoin is a decentralized electronic exchange system and represents a major change in the global financial system. Its system is based on peer-to-peer and cryptographic protocols and is not managed by any government or bank . It operates on the basis of a collusive and uncertain system in which all transactions are placed in an open ledger called blockchain . Due to limited resources, low transaction costs, and ease of transferring, Bitcoin has gained popularity rapidly in recent years across the globe. It has led to cryptocurrencies being recognized as an asset to the economy, and its reach extends to markets around the world . He said he thought Congress would ultimately have to address it because “there’s really not protection against fraud or manipulation.”
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.
By December, Bitcoin was on track to hit its all-time high thanks to a dramatic and steady increase in price. On Dec. 17, 2017, it reached $19,783.21, the all-time high that has yet to be broken. Unfortunately, that high was followed by a drop of about 30 percent, with a market correction that brought it down to under $11,000. In May, it hit $2,000 for the first time ever, and just a few weeks later, it was already over $3,000. Unsurprisingly, each new milestone was followed by a quick drop in price and other turbulence. Even so, the rally was enough to continue the upward trend, reaching $5,000 in September before dropping back to $3,000 and rebounding by mid-October. That would put Bitcoin as having around a $50 trillion market cap. At this point, all we need is to divide $50 trillion by the number of bitcoins in existence.
By mid-June of that year, Bitcoin was up to $320, an all-time high. At the moment of the statement, Bitcoin was traded over $11,000, days later it reached the lowest point in months when it was displayed in cryptocurrency exchanges under $6,000 dollars. The current valuation of Bitcoin is constantly moving, all day every day. From a start of under one cent per coin, BTC has risen in price by thousands of percent to the numbers you see above. The prices of all cryptocurrencies are quite volatile, meaning that anyone’s understanding of how much Bitcoin is will change by the minute. However, there are times when different countries and exchanges show different prices and understanding how much Bitcoin is will be a function of a person’s location. The current market cap of all global stock markets is around $100 trillion USD.
It uses a first-order differential equation to model the trend of time series. In June 2009, Nakamoto launched the peer to peer Bitcoin network that allows individual members of the network to track all transactions, and started to mine Bitcoin. During the early days of crypto mining, there were few miners in the network. Franco’s study used a Bitcoin data analysis and discovered that Nakamoto extracted nearly 1,000,000 Bitcoins. Interestingly, none of these Bitcoins had ever been spent, but the reason behind it is unknown. The creator of Bitcoin believes that within the next 10 years, digital currency will replace conventional currencies. Bitcoin is a digital currency that is not tied to a bank or government and allows users to spend money anonymously. The coins are created by users who “mine” them by lending computing power to verify other users’ transactions. The coins also can be bought and sold on exchanges with U.S. dollars and other currencies.

Trending Coins And Tokens

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.
Many crypto enthusiasts and economists believe that high-scale adoption of the top currency will lead us to a new modern financial world where transaction amounts will be denominated in smaller units. The digital payment company Square and its CEO Jack Dorsey — also the CEO of Twitter — have been big proponents of bitcoin. Overstock.com also accepts bitcoin, and in February, BNY Mellon, the oldest bank in the U.S., said it would include digital currencies in the services it provides to clients. And Mastercard said it would start supporting “select crypto currencies” on its network. In our model, the parameter a is the development index and b is the grey trigger value. The accuracy of the GM model depends on the values of a and b as well as the selection of the initial conditions during the modeling process.

McAfee was projecting $500,000 BTC in 2020 just a few weeks ago, but he modified his claim to be even more bold as bitcoin’s market surge has been moving faster than he anticipated. Love him or hate him, Adam Back is an OG cypherpunk who’s made incalculable contributions to the cryptocurrency space as a whole. There’s a reason Satoshi Nakamoto reached out to Back first in starting up Bitcoin. As such, you’ll commonly find him on Twitter making new price predictions based on the Bitcoin boom’s momentum.

Conclusion And Future Works

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.

This time, the crash occurred before Bitcoin reached its previous high. Once it hit $7.40, it went back to $3.80, a decline of 49 percent. But Mr Singh said that the kind of volatility that bitcoin experienced is not unusual nor unexpected. In the past, Bitcoin suffered important corrections in just a few days. In an even newer Twitter exchange, McAfee explained that he believes the BTC price could reach into the billions one day. That means the BTC could potentially shoot up exponentially in future years. Let’s take a look at some of the more prominent projections we’ve seen thrown around in recent days.
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.
There’s still quite the mountain to climb for the crypto market to get even close to hitting $100 trillion. Let’s go with 17 million instead of 21 million since many bitcoins have been lost already. Why would I go and grab some weird fiat subject to the will of some governments? That’s certainly the most aggressive price prediction anyone’s made for BTC yet. But if that insane price materializes, McAfee will end up looking like even more of a madman genius than he already is.

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.

As Bitcoin is used by ordinary people and because of its lack of relevance to other assets, Bitcoin has become an attractive option for investors. Therefore, the ability to predict prices would be a great help for investors. Considering the importance of the topic, many researchers have recently studied Bitcoin price prediction. Almeida et al. reviewed an artificial neural network model to predict the Bitcoin price using the last day price and turnover volumes. The main problem with their method is the requirement of a large amount data for the prediction. McNally’s research concerns predicting Bitcoin prices using machine learning.

Miners perform the calculation needed to record the data and a completed and verified process chooses a miner as the winner to update the blockchain. Each participant has a revised version of the audit, and therefore, the entire system is decentralized . Bitcoinis the original cryptocurrency released in 2009 as open-source software. It is a digital currency predicated on cryptographically secure transactions, a proof-of-work consensus model, and a decentralized, P2P distributed ledger network. To illustrate the robustness of the proposed method, predictions are done in a five-day time window, from July 18, 2010 to May 27, 2018. The average MAPE value is 1.14 for the last 2 months of the period.

The grey system theory is a non-statistical method of forecasting non-linear time series (Cen et al. 2006). The grey system theory was introduced by Deng in early 1982 and it quickly developed in the field of forecasting concerning—among others—economics, industry, and natural phenomena . The grey system theory is concerned about small samples and poor information and is classified according to the “colors” of systems. Black represents unknown information and white represents known information, while grey signifies information that are partially known (Deng 1989; Liu et al. 2012). The most recent exciting news in Bitcoin history began in November 2017 and led to the current all-time high for the cryptocurrency. In 2017, Bitcoin went from trading at just over $900 to about $20,000. This was a journey with many ups and downs along the way, a drop in trading volumes due to the People’s Bank of China tightening oversight of Bitcoin exchanges and the U.S. Securities and Exchange Commission rejecting a Bitcoin exchange-traded fund.

Those actions contributed to the run-up in bitcoin’s price, and Musk also promoted the digital currency Dogecoin, which also spiked in value. And China isn’t the only country clamping down on cryptocurrencies. Many banks in the Middle East are also barred from dealing in bitcoin, while U.S., regulators appear to be leaning toward more actively monitoring cryptocurrencies. On Thursday, the Treasury Department said it would require businesses to report any bitcoin payment over $10,000, citing an effort to crack down on tax evasion. Virtually every cryptocurrency fell after the industry group’s statement. Bitcoin slumped to $30,202 before recovering to $38,038, down 12% on the day, according to Coindesk. Most cryptocurrencies lost between 7% and 22% of their value and shares of Coinbase dropped 5.4%.

Domestic banks and other financial institutions from supporting bitcoin. That includes processing payments, allowing customers to hold bitcoin in their accounts and converting bitcoin into yuan or any other currency. A soft fork is a change to the Bitcoin protocol wherein only previously valid blocks/transactions are made invalid. Since old nodes will recognise the new blocks as valid, a soft fork is backward-compatible.

Bitcoin allows direct transactions between individuals, which is the main feature that distinguishes it from traditional currencies. The fact that Bitcoin does not need third-party agencies is one of the reasons for its popularity. This unique characteristic means that the entire system is decentralized . The network assumes that most nodes—which are, in fact, individuals—are honest and intercepts all transactions. The Bitcoin system does not have a mediating entity and no third party for managing transactions; therefore, several existing nodes process each transaction. These nodes are responsible for registering each transaction in a public ledger called a blockchain. The nodes that process transactions are called “miners” and the process “mining.” As compensation for the registration of each transaction in the blockchain, a reward is given to the miner.

Some of the top crypto hot wallets include Exodus, Electrum and Mycelium. Over the years a large number of people have contributed to improving the cryptocurrency’s software by patching vulnerabilities and adding new features. In 2016, An Australian entrepreneur stepped forward and claimed to be the founder of bitcoin, only to say days later that he did not “have the courage” to publish proof that he is. Regulators aren’t very worried about a possible crash in digital currencies dragging down the rest of the financial system or economy. Bitcoins are basically lines of computer code that are digitally signed each time they travel from one owner to the next. Transactions can be made anonymously, making the currency popular with libertarians as well as tech enthusiasts, speculators — and criminals. There was some trading stabilization in January 2014, with the price staying about $920. When Mt. Gox filed for bankruptcy protection in February, another Bitcoin crash occurred. Between Feb. 4 and 16, it declined about 71 percent from $911 to $260. Following this dramatic fall, investors were hesitant about Bitcoin.

Some businesses take bitcoin as payment, and a number of financial institutions allow it in their clients’ portfolios, but overall mainstream acceptance is still limited. Cryptographic currencies represent a growing asset class that has attracted much attention from financial communities. Cryptocurrencies are digital cash and payment systems that are encrypted in a blockchain system . The four main cryptocurrencies currently on the market are Bitcoin, Ethereum, Ripple, and Litecoin. Bitcoin, Etherum, and Litecoin use the same network of computers to store the same copies of all transactions. Therefore, the possibility of any anomalies is highly unlikely and the network is completely safe (Iwamura et al., 2019). Bitcoin is currently trading at the top of the cryptocurrencies list. Moreover, Bitcoin’s algorithm is used in most cryptocurrencies (Gandal & Halaburda, 2016). This study aimed to investigate the potential application of the grey system theory in Bitcoin price prediction. We consider a period of 5 days and another period of 6 months for the prediction.
