The volatile behavior of Bitcoin's price, especially during its halving periods, poses considerable obstacles for forecasting and decision-making in cryptocurrency trading. This paper presents a novel method that combines application fuzzy logic with Bollinger Bands to improve trading decision-making in times of high market volatility. This study conducted an experiment utilizing three fuzzy logic controllers and Bollinger Bands (BB) to determine the strength of buy, hold, and sell signals. This dataset includes the initial and final prices that are used to calculate the BB. The raw and computed values serve as the precise input parameters for the Fuzzy Inference System (FIS). The membership functions were categorized into four levels: very low, low, high, and very high, based on the input default settings utilized by traders. Rulesets were created using fuzzy logic to produce signals that indicate the level of strength of a trading advice. This study evaluate the effectiveness of this hybrid method in comparison to the traditional utilization of the Bollinger Band only indicator and Moving Average Convergence Divergence (MACD) indicator, which is widely favored by traders to identify possible market fluctuations. This methodology involves creating a trading simulation that is based on past Bitcoin halving events. The objective is to assess the efficacy of these strategies in managing heightened volatility. The application of fuzzy logic with the Bollinger Bands model yielded a success rate of 92.47% while analyzing 93 daily data points from the previous Bitcoin halving event on May 11, 2020.

Blockchain technology is one of the most novel technologies that received attention from academia and practitioners in various industries because of its profound nature and the opportunities that it offers, especially in the digital age. Ethereum, which is the largest decentralized blockchain software, was introduced in 2015 and is best known for its smart contracts that facilitate different utilizations over its blockchain network. Also, it can be used as a cryptocurrency, and historically it has been the 2nd most valuable cryptocurrency following Bitcoin. In order to be able to use Ethereum smart contracts over the blockchain network, a transaction fee or a gas fee is set by the network according to that specific task. This study is aimed to develop Machine Learning (ML) models to predict the Ethereum gas fee by using a comparison of Long Short-Term Memory (LSTM) and the Facebook Prophet Model (FPM). The gas fee prediction modeling was done based on the daily dataset of eight years from 2015 to 2022. The results in this study showed that the FPM model in the scenario of this study resulted in a Mean Absolute Error (MAE) of 0.02 and a Root Mean Squared Error (RMSE) of 0.05. However, MAE and RMSE values of the LSTM model turned out equal to 0.006 which showed a higher performance and more accuracy compared to the FPM model.

Abstract This research proposes a system to store transaction records from a payment gateway based on digital payments by utilizing blockchain technology and Interplanetary File System (IPFS) as distributed storage. In digital payments, the possibility of online fraud or theft of customer data is a problem that needs to be solved. Although the solution is to use a Payment Gateway with security standards to prevent these problems, the system is still centralized and vulnerable to the possibility of system failure or data changes by irresponsible people. Blockchain furnishes a secure and unalterable record for documenting payment transactions. Conversely, IPFS presents a decentralized and immune-to-censorship approach for storing and accessing data. The usage of these technologies guarantees the secure storage of payment transaction data and related documents (such as invoices and receipts) while effectively thwarting data manipulation or censorship attempts. Therefore, this research aims to build a blockchain technology system to increase security and maintain the integrity of the data generated from the Payment Gateway. This research using distributed data storage using IPFS to save transaction from the payment gateway data. Based on the evaluation and security analysis results, implementing a blockchain technology system to store transaction records from digital-based payment gateways can improve data security and integrity. In the gas fee increase analysis, the gas fee will increase according to the total number of bytes generated when the transaction is made, where each byte will cost 12 gwei to pay the gas fee.
