1. Abstract

Cryptocurrency has emerged as a significant financial asset class with the rapid advancement of blockchain technology. Among various cryptocurrencies, Ethereum is one of the most widely used decentralized platforms, known for its smart contract functionality and active trading market. Due to its highly volatile and dynamic nature, predicting Ethereum prices has become a challenging time series forecasting problem.

This project focuses on predicting Ethereum closing prices using Long Short-Term Memory (LSTM) networks, a specialized type of Recurrent Neural Network (RNN) designed to handle sequential and time-dependent data. The dataset used in this project is publicly available on Kaggle and contains hourly Ethereum price data from May 2016 to April 2020.

Data pre-processing techniques such as handling missing values, scaling, and transforming time series data into supervised learning format are applied. The LSTM model is trained to capture temporal dependencies and price trends. Finally, the trained model is deployed as a Flask-based web application, allowing users to input previous price data and obtain predicted Ethereum closing prices.

This project demonstrates the practical application of deep learning techniques in financial time series forecasting and cryptocurrency trend analysis.

 2. Objectives

The main objectives of this project are:

1. To understand cryptocurrency as a time series forecasting problem.
2. To study Ethereum and analyse its market behaviour.
3. To explore historical price trends and volatility patterns.
4. To pre-process and prepare sequential time series data for deep learning models.
5. To understand Recurrent Neural Networks (RNNs).
6. To study and implement Long Short-Term Memory (LSTM) networks.
7. To train and evaluate an LSTM model for Ethereum price prediction.
8. To deploy the trained model as a Flask-based web application.

3. Existing System

Traditional cryptocurrency price prediction methods rely on:

1. Manual technical analysis and chart pattern study
2. Statistical models such as ARIMA and regression models
3. Basic machine learning algorithms

Limitations of Existing Systems:

1. Difficulty in handling highly volatile market behaviour.
2. Inability to capture long-term temporal dependencies effectively.
3. Lower accuracy in sequential financial forecasting.
4. Limited real-time deployment and interactive prediction systems.
5. High dependency on human interpretation in manual analysis.

These limitations create the need for more advanced deep learning-based forecasting techniques.

 4. Proposed System

The proposed system predicts Ethereum closing prices using deep learning techniques, specifically LSTM networks.

In this system:

1. Historical Ethereum price data is collected from Kaggle.
2. Time series data is cleaned and normalized.
3. Sequential training data is prepared using a sliding window approach.
4. A Long Short-Term Memory (LSTM) neural network is developed.
5. The model learns patterns and temporal dependencies in historical prices.
6. Future closing prices are predicted based on previous price sequences.
7. The trained model is deployed using Flask as a web application.

This system provides automated, data-driven, and real-time cryptocurrency price prediction.
