本研究所採用樣本主要選取比特幣 (BTC)、以太幣 (ETH)、幣安幣 (BNB),研究期間為2017年 11 月9日到 2023 年 10 月 31日,選取三個虛擬貨幣之日資料計1504筆,並且運用了多種的時間序列計量方法,用以驗證三種加密貨幣之間是否存在因果關係,並探討比特幣是否具有預測主要虛擬貨幣市場的能力。實證結果顯示,這三種加密貨幣之間存在共整合關係,代表這三個虛擬貨幣之間有長期均衡關係,投資人無法藉由投資這三個虛擬貨幣來達到充分分散風險的效果。因此,研究使用了向量誤差修正模型(VECM)更加進一步分析,以評估其價格報酬之間是否存在顯著的因果關係。在Granger的因果檢定下,結果顯示整體的比特幣 (BTC)報酬預測能力,可以影響以太幣 (ETH),卻不能影響幣安幣 (BNB);以太幣 (ETH)報酬,可以影響幣安幣 (BNB),卻不能影響比特幣(BTC):而幣安幣 (BNB)完全無法影響比特幣 (BTC)與以太幣 (ETH)。
This study examines the causal links between Bitcoin (BTC), Ethereum (ETH), and Binance Coin (BNB) in the virtual currency market. Using a dataset spanning from November 9, 2017, to October 31, 2023, with 1504 daily observations for BTC, ETH, and BNB, we apply various time-series econometric methods to explore their relationships.Results indicate a long-term stable connection among the three cryptocurrencies, prompting the use of a Vector Error Correction Model (VECM) for regression analysis. Granger causality tests reveal that Bitcoin's return predictions influence Ethereum but not Binance Coin, while Ethereum returns impact Binance Coin but not Bitcoin. Binance Coin does not exert influence on either Bitcoin or Ethereum.In summary, our findings suggest intricate causal relationships among these cryptocurrencies, highlighting Bitcoin's potential as a predictor in the virtual currency market.
