This paper proposes a new machine learning (ML) model to predict the percentage change of a certain cryptocurrency within a day or a week using sentiments, subjectivity, ticker mention and other parameters that can be extracted from users' activity on different crypto community platforms such as Reddit and Bitcointalk. The results show quite good correlation between these parameters and the price change, and in almost 85% of the cases the price is moving into the predicted direction. © 2023 American Institute of Physics Inc..
