--The rapid growth of the stock market has attracted many investors due to its potential for significant profits. However, predicting stock prices accurately is difficult because financial markets are complex and constantly changing. This is especially true for the cryptocurrency market, which is known for its extreme volatility, making it challenging for traders and investors to make wise and profitable decisions. This study introduces a machine learning approach to predict cryptocur-rency prices. Specifically, we make use of important technical indicators such as Exponential Moving A verage (EMA) and Moving A verage Convergence Divergence (MACD) to train and feed the XGBoost regressor model. We demonstrate our approach through an analysis focusing on the closing prices of Bitcoin cryptocurrency. We evaluate the model's performance through various simulations, showing promising results that suggest its usefulness in aiding/guiding cryptocurrency traders and investors in dynamic market conditions. Over the past few years, the rapid expansion of the stock market has made it an appealing option for investors seeking high returns and easy access.

Prediction of stock prices has been a crucial and challenging task, especially in the case of highly volatile digital currencies such as Bitcoin. This research examineS the potential of using neural network models, namely LSTMs and GRUs, to forecast Bitcoin's price movements. We employ five-fold cross-validation to enhance generalization and utilize L2 regularization to reduce overfitting and noise. Our study demonstrates that the GRUs models offer better accuracy than LSTMs model for predicting Bitcoin's price. Specifically, the GRU model has an MSE of 4.67, while the LSTM model has an MSE of 6.25 when compared to the actual prices in the test set data. This finding indicates that GRU models are better equipped to process sequential data with long-term dependencies, a characteristic of financial time series data such as Bitcoin prices. In summary, our results provide valuable insights into the potential of neural network models for accurate Bitcoin price prediction and emphasize the importance of employing appropriate regularization techniques to enhance model performance.

Bitcoin, as one of the most popular cryptocurrency, is recently attracting much attention of investors. Bitcoin price prediction task is consequently a rising academic topic for providing valuable insights and suggestions. Existing bitcoin prediction works mostly base on trivial feature engineering, that manually designs features or factors from multiple areas, including Bticoin Blockchain information, finance and social media sentiments. The feature engineering not only requires much human effort, but the effectiveness of the intuitively designed features can not be guaranteed. In this paper, we aim to mining the abundant patterns encoded in bitcoin transactions, and propose k-order transaction graph to reveal patterns under different scope. We propose the transaction graph based feature to automatically encode the patterns. A novel prediction method is proposed to accept the features and make price prediction, which can take advantage from particular patterns from different history period. The results of comparison experiments demonstrate that the proposed method outperforms the most recent state-of-art methods.

Bitcoin is a very particular asset. Bitcoin is a very particular asset. Its price is sensible to demand and supply rather than external factors, so it may highly depend on perceived trends rather than perceived information. For this category of problems, pattern recognition may prove incredibly useful. Because this problem is very big, from beginning to end, I will begin with the first part of the article by Mining Bitcoin Data.

The November 2017 intense discussions around Bitcoin grabbed my attention and I decided to dive deep into understanding what exactly is this. I read a bunch of papers, several books and many opinions on the topic in order to get a decent understanding of its value in the current market. You have probably heard of Bitcoin, but if you want to fully acknowledge its existence, I recommend reading Andreas' book -- The Internet of Money. Of course, the thing that is most attractive to the vast majority of people is the price volatility of this asset. The increase/decrease in Bitcoin's price with large percentages over short periods of time is an interesting phenomenon which cannot be predicted at all.
