虛擬貨幣的可投資性研究-以比特幣為例

Study on the feasibility research of virtual currency-The case study of Bitcoin

指導教授 : 胡為善

摘要


隨著高科技的迅速發展,人們的付款方式逐漸改變。由於網路的發達,使得許多企業採用網路購物及網路付款的方式,甚至有些企業家從而發現網路商機,推出屬於自己平台專用的虛擬貨幣。尤其近幾年,隨著比特幣的逐漸盛行,更使虛擬貨幣成為眾所矚目的交易工具。本研究之目的旨在探討虛擬貨幣是否能成為投資工具,並特以比特幣為例,研究期間自2013年10月04日起至2015年3月20日,同時探討黃金及現行重要貨幣(例如歐元及日圓)是否可預測比特幣之波動。由於比特幣自2013年10月起才發生明顯波動,在2013年11月至2014年1月達高峰後開始緩慢下跌,本研究以2014年9月26日為分水嶺,將其前後各分一段,2013年10月4日至2013年9月26日為前段,此期間為比特幣波動的高峰期,後段則自2014年9月29日起至2015年3月20日止,該期間為比特幣波動的趨緩期。本研究採用單根檢定、共整合檢定、VAR及因果關係檢定等方法,以查驗黃金、歐元與日圓能否預測比特幣之波動情形。實證結果顯示,在全樣本期間,只有日圓為影響比特幣的因,但影響不大,其餘皆與比特幣無因果關係,因此可知虛擬貨幣在現階段的波動與黃金及主要貨幣無關,較可能與消息炒作相關。

Along with the rapid advancement of industrial technology, people change their payment habits and methods gradually. The fast progress of internet allows various companies to use online purchasing and network payment. As the rapid development of Bitcoin for the past decade, many entrepreneurs found internet opportunities and launched their own platform-specific virtual currency. This study thus attempts to examine whether the virtual currency can be an investment instrument. During the sample period of October 4, 2013 to March 20, 2015, this study uses Bitcoin as a target to examine whether the gold and major currency (i.e., Euro dollar and Japanese yen) can forecast the fluctuations of Bitcoin. This investigation then classifies the study period into two sub-periods as follows: one runs starts from October 4, 2013 to September 26, 2014, which denotes the dramatic fluctuation of the Bitcoin; another one runs from September 29, 2014 to March 20, 2015, which demonstrates the minor fluctuation of the Bitcoin. This study then examines whether gold and major currencies can predict the fluctuations of the Bitcoin by using ADF test, co-integration test, VAR and Granger causality test. Empirical results show that only the Japanese yen majorly affects the Bitcoin during the full sample period. This finding demonstrates that the change of the gold price and that of the foreign currency of major countries do not have significant impact on the fluctuation of the Bitcoin. However, it implies that the fluctuation of the Bitcoin was caused by the relevant news regarding the Bitcoin.
