title: Bitcoin, USDT, and DAI Daily Market Data (2020–2025)

description: Three datasets are released as part of my Master’s Thesis (Analysis of Centralized and Decentralized Stablecoins: A Comparative Study of USDT and DAI, Complutense University of Madrid, 2025).

The datasets provide daily historical market data for Bitcoin (BTC), Tether (USDT), and DAI, covering the period May 1st, 2020 – May 1st, 2025 (UTC). Data were retrieved from the CoinDesk Index CC API, using the endpoint index/cc/v1/historical/days , with full OHLC (Open, High, Low, Close) information, trading volume, and microstructure activity indicators.

Files





df_bitcoin.csv: Daily market data for Bitcoin (BTC-USD).




df_usdt.csv: Daily market data for Tether (USDT-USD).




df_dai.csv: Daily market data for DAI (DAI-USD).



Columns





DATE: UTC timestamp (daily frequency).




OPEN: Opening price of the asset.




HIGH: Daily maximum price.




LOW: Daily minimum price.




CLOSE: Closing price.




VOLUME: Daily trading volume.




TOTAL_INDEX_UPDATES: Number of index updates per day (proxy for market activity).



Purpose

These datasets were used to construct three measures of stability and market activity:





M1 – Deviation from the $1 peg (CLOSE - 1).




M2 – Realized volatility (Parkinson estimator).




M3 – Market activity (TOTAL_INDEX_UPDATES).



They were then analyzed with econometric methods such as ADF stationarity tests and VAR (Vector Autoregression) models with orthogonalized Impulse Response Functions (IRFs), in line with previous academic literature.

title: Use of on-demand digital services, adoption factors, and perceptions of time

description: On-demand digital services offer fast fulfilment of various products and services through digital technologies. This business model has spread across media, mobility, food, grocery, and retail, attracting millions of consumers to services such as Netflix, Uber, Deliveroo, and Amazon Prime. The expansion of such services is transforming the consumption experience with significant social and environmental implications.

This repository contains raw data from a cross-sectional survey with UK residents (n=1,512) that investigated people’s use and adoption of various on-demand digital services. The survey compared adopters and non-adopters of three popular on-demand digital services: online food delivery, next day delivery retail, and ride-hailing. The survey included questions around innovation attributes, perceptions of time (pace of life and time scarcity), impulse buying, attitudes towards digital technology, digital services use, and contextual sociodemographic factors.
