Öz

The significance of social media in influencing cryptocurrency pricing has grown considerably in recent years. This study aims to explore the correlations between social media sentiments and Bitcoin pricing, both in the short and long terms, while also investigating the direction of these relationships. Sentiment analysis was conducted using the TextBlob model, which uncovers the underlying meaning in text through analysis. The study tested the hypothesis that there exists a relationship between sentiment analysis scores and Bitcoin prices over both short and long periods. Ensuring stationarity was crucial for time series analysis, involving the use of structural break and traditional unit root tests. Daily data from June 2021 to June 2022 was examined, with December 2021 serving as the focal point due to a peak in Bitcoin prices. The study focused on Bitcoin price data and sentiment analysis scores. Results revealed Twitter data as the dependent variable, showing no long-term relationship with Bitcoin prices. However, a significant and positive relationship was observed in the short term. This research contributes valuable insights into the intricate dynamics between social media sentiments and cryptocurrency pricing.

Sosyal medyanın kripto para birimi fiyatlandırmasını etkilemedeki önemi son yıllarda önemli ölçüde artmıştır. Bu çalışma, sosyal medya duyarlılığı ile Bitcoin fiyatlandırması arasındaki ilişkileri hem kısa hem de uzun vadede araştırmaktadır. Aynı zamanda bu ilişkilerin yönünü tespit etmeyi amaçlamaktadır. Duyarlılık analizi, metnin altında yatan anlamı ortaya çıkaran TextBlob modeli kullanılarak gerçekleştirilmiştir. Çalışma, duyarlılık analizi puanları ile Bitcoin fiyatları arasında hem kısa hem de uzun vadede bir ilişki olduğu hipotezini test etmiştir. Durağanlığın sağlanması, yapısal kırılma ve geleneksel birim kök testlerinin kullanımını içeren zaman serisi analizine imkan sağlamıştır. Çalışma kapsamındaHaziran 2021'den Haziran 2022'ye kadar olan günlük veriler incelenmiştir ve Bitcoin fiyatlarındaki zirve nedeniyle Aralık 2021 odak noktası kabul edilmiştir. Çalışma Bitcoin fiyat verilerine ve duyarlılık analizi puanlarına odaklanmaktadır. Sonuçlar, Bitcoin fiyatlarıyla uzun vadeli bir ilişki göstermeyen Twitter verilerinin bağımlı değişken olduğunu ortaya çıkarmıştır. Ancak kısa vadede anlamlı ve pozitif bir ilişki gözlenmiştir. Bu araştırma, sosyal medya duyarlılığı ile kripto para birimi fiyatlandırması arasındaki karmaşık dinamiklere dair literatüre değerli bilgiler sağlamaktadır.
