AB  - Volatility is essential when trading or investing in cryptocurrency Ethereum.
Over the years, investors, traders and investment banks have found it difficult
to predict the price volatility of Ethereumdue to its rapid price fluctuation.
This report focuses on forecasting the price volatility of Ethereum for the next
two days using daily historical observations of the price of Ethereumobtained
from Coindesk and tweets extracted from Twitter ranging from the 1st of
August 2022 to the 8th of August 2022. Two models are used to compute the
forecast for the next two days: support vector regression and recurrent neural
network. The main evaluationmetric used is the mean absolute error. In this
study, according to MAE, RNN without tweets forecasts outperformthe SVR
model without tweets forecasts, with the best model being the RNN without
tweets producing an MAE of 0.0309.&#xd;
