Finansal varlıkların gelecekteki değerlerinin tahmini yatırımcılar için varlıklarını korumak adına önemlidir. 2008 yılında hayatımıza giren ve finansal varlıklar konusunda radikal bir değişiklik olan Bitcoin ise eski ve yeni yatırımcıların ilgisini çekmiş durumdadır. Ancak Bitcoin, doğası gereği diğer finansal varlıklara göre değerini belirleyen farklı parametreler içermektedir ve geleneksel tahmin yöntemleri Bitcoin gibi çok hareketli değerlere sahip finansal varlıkları tahmin etmekte güçlük çekmektedir. Bu çalışmada çok değişkenli LSTM sinir ağı ve klasik ARIMA zaman serisi modeli kullanılarak Bitcoin’in gelecek değerinin tahmini için modeller geliştirilmiştir. Uygulanan iki modelin tahmin doğruluğu performans değerlendirme metrikleri olan hata metrikleri kullanılarak karşılaştırılmıştır. Deneysel çalışmalar sonucu, LSTM sinir ağı modeli yakın ve uzak gelecek için düşük hata oranı ile tahmin performansı gerçekleştirirken ARIMA zaman serisi modeli yakın gelecek tahmini için düşük hata oranı ile tahmin performansı gerçekleştirmiştir.

It is important to forecast the future value of financial assets for investors to protect their assets. Bitcoin, which introduced to our lives in 2008 and is a radical change in financial assets, has been attracted the attention of both old and new investors. However, by its nature, Bitcoin contains different parameters that determine its value compared to other financial assets, and traditional forecasting methods have difficulty in predicting future values with very volatile financial assets such as Bitcoin. In this study, multivariate LSTM neural network and classic ARIMA time series model to forecast the future value of Bitcoin have been developed. The prediction accuracy of the two models applied has been compared using error metrics, which are performance evaluation metrics. As a result of the experimental studies, the LSTM neural network model has been performed prediction performance with a low error rate for the near and far future, while the ARIMA time series model has been performed prediction performance with a low error rate for the near future prediction.
