Thus, it is of great importance to pay attention to these predictive models when constructing portfolio with a historical average benchmark model; on the other hand, when constructing portfolio with AR 4 benchmark model, asymmetrical forecasting model outperforms other models including the AR benchmark model, which indicates that the predictive model surely bring economic values.

Furthermore, the main results cannot be altered by the change of transaction cost, which means that our results are robust. To sum up, using investor attention to predict the return of Bitcoin asset can bring significant economic benefits based on allocation exercises and results do not vary across different benchmark models. In this paper, we focus on the relationships between Bitcoin market and the novel investor attention to fill the current potential research gap.

First, we conduct the basic linear granger causality test and the corresponding VAR analysis. The results show that investor attention is indeed the granger cause of Bitcoin market both in return and realized volatility, and the shock from investor attention can last for several weeks in Bitcoin market. Second, we analyze the nonlinear connections between the two markets, i. The results show sophisticated non-linear relationships both for Bitcoin return and realized volatility.

Third, we implement one basic and several longer-horizon out-of-sample forecasts to fully explore the relationships between investor attention and Bitcoin market, specifically for the forecasting abilities of investor attention. The results show that regarding the Bitcoin return, incorporating the investor attention surely improve the forecasting accuracy.

However, predictive models with investor attention do not outperform the benchmark model regarding the Bitcoin realized volatility.

Finally, we conduct asset allocation by constructing risky investment portfolios consist of Bitcoin asset and a risk-free asset to analyze the economic values of out-of-sample forecasts. The results show that compared with the historical average benchmark model and the AR benchmark model, the Bitcoin earnings forecasts based on investor attention have significant economic values as the Sharpe ratio is indeed increased. In summary, investor attention is a non-negligible factor in Bitcoin market. However, there are some disadvantages regrading this paper. For example, in our empirical analysis, the OLS estimation methodology is mainly used to investigate the influence of investor attention.

In the future, attempts to adopt other methods may be studied. In addition, this article mainly focuses on investor attention closely related to the Bitcoin market, investor attention on other markets, i. These defects deserve in-depth studies in the future.

High order moment Inspired by other researchers exploring the relationships between high order moments of investor attention and assets [ 88 ], we further conduct the related empirical investigations on this issue.

Interactive relationship Inspired by existing research [ 87 ], we have also incorporated the interactive terms of lagged investor attention with Bitcoin return or realized volatility into our models to further explore the relationships between investor attention and Bitcoin market.
