Can investors’ informed trading predict cryptocurrency returns? Evidence from machine learning?5 answersInvestors' informed trading can predict cryptocurrency returns to a certain extent, as evidenced by machine learning techniques. Studies show that machine learning algorithms, including support vector machines, logistic regression, artificial neural networks, and random forests, achieve an average classification accuracy above 50% for various cryptocurrencies at daily and minute frequencies. Additionally, active trading models based on reinforcement machine learning demonstrate enhanced risk-adjusted returns for major cryptocurrencies, reducing downside risk compared to buy-and-hold strategies. However, predicting cryptocurrency movements with machine learning algorithms is challenging due to the complex nature of return generation, hidden risks, and varying predictability across different cryptocurrencies and information sets. Despite limitations in accuracy, machine learning models offer valuable tools for anticipating cryptocurrency returns and aiding market analysis.

CNNs have shown excellent performance in image categorization due to their local connectivity, weight sharing, pooling operations, and multilayer structures. Transformer-based models, such as the Visual Transformer (ViT) and data-efficient image transformer, have also achieved significant breakthroughs in image classification accuracy. These algorithms have revolutionized the field of computer vision by effectively handling complex images and large-scale datasets, making them essential tools for researchers and practitioners in image classification tasks.
Can the use of machine learning algorithms help in predicting raw returns for different cryptocurrencies and improve investment strategies?4 answersMachine learning algorithms have been explored for predicting raw returns of different cryptocurrencies and improving investment strategies. Various studies have tested the prediction accuracy of cryptocurrency returns using algorithms such as decision trees, random forests, ensemble methods, SVM, neural networks, N-BEATS, ARIMA, and Google AutoML. These studies have shown that while predicting cryptocurrency returns is possible, the algorithms may not generalize well for different assets and markets over long periods. However, despite the low accuracy and precision rates, machine learning models have been able to anticipate bitcoin returns using classification and regression techniques. Additionally, the application of machine learning strategies, such as arbitrage and trend strategies, has been compared to analyze and predict the future of Bitcoin's investment. Overall, machine learning algorithms have shown potential in predicting cryptocurrency returns and improving investment strategies, but the choice of algorithm depends on user needs and available resources.
How can machine learning and deep learning be used to predict the price of digital currencies?4 answersMachine learning and deep learning techniques, such as LSTM and RNN, can be used to predict the price of digital currencies. These methods analyze historical data, including factors like close price, trading information, and technical indicators, to forecast future prices and price movements. Various state-of-the-art deep learning models, including LSTM, convolutional neural networks, and deep residual networks, have been compared for cryptocurrency price prediction. The prediction accuracy can be improved by selecting relevant features with strong correlation to cryptocurrency prices and training the model with suitable data chunks. Additionally, deep learning algorithms and analysis of distinguishing features can be used to predict the closing price of cryptocurrencies at a particular time. These techniques can be combined with sentiment analysis and other factors like total circulating supply and production costs to determine the factors influencing cryptocurrency prices and make accurate predictions.
