This study aims to investigate Bitcoin price and its fluctuation using grey system theory. Therefore, studying its prediction is of great importance and researchers are becoming focused on it. Interestingly, based on the information provided from the website Bitcoin has more than 50% of the market share in the cryptocurrency market at the time of this study. Due to its unstable nature, cryptocurrency prediction is not an easy task. ( 2010).īitcoin is a fresh market that is still in its transition phase therefore, a lot of fluctuations can still be observed (Briere et al. More details can be found in other works, such as Cocianu and Grigoryan ( 2015) and Ma et al. ( 2016) investigated share market prediction. Alrasheedi and Alghamdi ( 2012) used a linear discriminant and logit model to predict the SABIC (Saudi Basic Industries Corporation) price index, and Sathe et al. It presents a hybridized approach which combines the use of the variables of technical and fundamental analysis of stock market indicators for prediction of future price of stock in order to improve on the existing approaches. ( 2012) used a neural network to predict stock prices. 2019) however, it has been extensively investigated by researchers. Stock market prediction is difficult due to its volatile and changeable nature (Kou et al. It has led to cryptocurrencies being recognized as an asset to the economy, and its reach extends to markets around the world (Hayes 2016). Due to limited resources, low transaction costs, and ease of transferring, Bitcoin has gained popularity rapidly in recent years across the globe. It operates on the basis of a collusive and uncertain system in which all transactions are placed in an open ledger called blockchain (Guo and Liang 2016). Its system is based on peer-to-peer and cryptographic protocols and is not managed by any government or bank (Vidal 2014). 2017).īitcoin is a decentralized electronic exchange system and represents a major change in the global financial system.
Each cryptocurrency has its own rules concerning the maximum amount of money, currency production, privacy, transaction rates added to the blockchain, and the various mechanisms used by miners to compete among each other and earn rewards (Indera et al. Moreover, Bitcoin’s algorithm is used in most cryptocurrencies (Gandal & Halaburda, 2016). Bitcoin is currently trading at the top of the cryptocurrencies list. Therefore, the possibility of any anomalies is highly unlikely and the network is completely safe (Iwamura et al., 2019). Bitcoin, Etherum, and Litecoin use the same network of computers to store the same copies of all transactions. The list is constantly changing as investors grow. The four main cryptocurrencies currently on the market are Bitcoin, Ethereum, Ripple, and Litecoin. Cryptocurrencies are digital cash and payment systems that are encrypted in a blockchain system (Hayes 2016). The results show that the GM (1,1) model predicts Bitcoin’s price accurately and that one can earn a maximum profit confidence level of approximately 98% by choosing the appropriate time frame and by managing investment assets.Ĭryptographic currencies represent a growing asset class that has attracted much attention from financial communities. It uses a first-order differential equation to model the trend of time series. The first order grey model (GM (1,1)) is used for this purpose. The purpose of this study is to predict the price of Bitcoin and changes therein using the grey system theory.
While considerable research has been done concerning Bitcoin network analysis, limited research has been conducted on predicting the Bitcoin price. Moreover, Bitcoin has made itself the dominant source of decentralized cryptocurrency. In recent years, the Bitcoin network has attracted investors, businesses, and corporations while facilitating services and product deals. Cryptocurrency allows users to safely and anonymously use the Internet to perform digital currency transfers and storage. Bitcoin is currently the leading global provider of cryptocurrency.
