*4.3. Proposed Comparative Analysis for Dataset 2*

According to the theoretical analysis regarding demand and supply theory and costbased pricing theory, macroeconomic and blockchain information indicators do not have short-term predictability power on BTC prices. For the empirical analysis, a comparative machine learning model, including OLS, Ensemble methods, SVR, and MLP for the BTC price prediction problem on datasets from 1 January 2018 to 5 June 2018, including macroeconomic, microeconomic, technical indicators, and blockchain information indicators. Feature selections, namely best first search, PSO search, and evolutionary search, are applied to the data. The price prediction model is described in the Appendix A (model 3).
