The results showed that Capital Expenditure had no partial effect on Financial Performance, Size of Local Government partially affected Financial Performance, and the Remaining Budget Financing partially affected Financial Performance. Partially, Capital Expenditure, Size of Local Government, and Remaining Budget Financing together have an effect on the Financial Performance of district/city governments in North Sumatra Province. The R-Square value is 0.815 or 81.5%. This shows that the variables of Capital Expenditure, Size of Local Government, and Remaining Budget Financing are able to explain the Financial Performance variable of 81.5%. While the remaining 18.5% is explained by other variables outside the study.

Abstract

The cryptocurrency market, particularly Bitcoin, exhibits extreme volatility, necessitating robust forecasting tools for informed trading decisions. This study aimed to evaluate the performance of linear regression and trend moment models in predicting Bitcoin prices using daily data from 2022 to 2024. Historical closing prices were collected from reliable cryptocurrency exchanges, cleaned to ensure consistency, and augmented with relative strength index and moving average convergence divergence indicators to enhance predictive accuracy. The models were trained on 2022–2023 data and tested on 2024 data, with forecasting accuracy measured using the Mean Absolute Percentage Error metric. The findings revealed that linear regression achieved a lower error rate of 36.44% compared to Trend Moment’s 39.21%, demonstrating superior performance in stable and trending market conditions. Both models struggled with volatile price swings, though linear regression proved more adaptable when incorporating technical indicators. These results suggest that linear regression offers a practical, computationally efficient solution for short-term Bitcoin price forecasting, particularly for retail traders. Future research could explore hybrid models or additional predictors to improve accuracy in volatile markets, contributing to accessible forecasting tools for the cryptocurrency domain.
