“…The forecastability of cryptocurrencies' price movements and the profitability of trading strategies have also been addressed using Machine Learning tools, such as Binomial Logistic Regressions (Madan et al, 2015), Random Forests (Madan et al, 2015;Vo and Yost-Bremm, 2018;Xiaolei et al, 2018), Decision Trees (Huang et al, 2018;Xiaolei et al, 2018;Alessandretti et al, 2018), Support Vector Machines (Żbikowski, 2016;Xiaolei et al, 2018;de Souza et al, 2019;Mallqui and Fernandes, 2019), and Artificial Neural Networks Liang, 2017, McNally et al, 2018;Jang and Lee, 2018;Nakano et al, 2018;de Souza et al, 2019;Mallqui andFernandes, 2019¸ Lahmiri andBekiros 2019), particularly Long Short-Term Memory Networks (McNally et al, 2018, Alessandretti et al, 2018Lahmiri and Bekiros, 2019). Most of these papers use Bitcoin daily price data, but some of them use high-frequency data or data on other cryptocurrencies.…”
