Swiss cryptocurrency Cardano (ADA) witnessed a price surge of nearly 100 percent in seven days in early February 2021, amid high interest from investors. One reason for this interest is the digital coin's close relation to Ethereum (ETH), as mathematician Charles Hoskinson co-founded both virtual currencies. Also, like Ethereum, ADA has an open-source format, meaning anybody can develop this currency further. As of July 15, 2025, one ADA token was worth 0.73 U.S. dollars.
Cardano network fees paid to miners whenever a payment transaction is initiated on the blockchain stayed roughly the same for months - although the coin value did change. These transaction fees - commonly denoted as gas - changed especially since the summer 2021, when the price of the ADA coin was changing. This coincided with the growing importance of Decentralized Finance or DeFi, and more blockchains being used for the development of new financial applications.
The market cap of Cardano (ADA) nearly doubled in **** days in February 2021, amidst a growing buying activity from investors during this time. Cardano stood out due to its close relation to Ethereum, as well as a detailed transaction history in its ledger - potentially making this digital coin more secure than others. Compared to both the Bitcoin market capitalization, as well as the Ethereum market cap, Cardano was not as popular.
By November 2021, over 33 billion Cardano tokens were issued and in active circulation - getting closer to the coin's maximum supply. Similar to Bitcoin but unlike Ethereum, the ADA token has a fixed supply limit with only 45 billion cryptocurrencies being able to ever exist in the coin's lifetime. Whilst this does not necessarily mean the Cardano price will go up, a limited supply could help to fuel demand whilst the tokens are still generally available.

Cryptocurrency historical datasets from January 2012 (if available) to October 2021 were obtained and integrated from various sources and Application Programming Interfaces (APIs) including Yahoo Finance, Cryptodownload, CoinMarketCap, various Kaggle datasets, and multiple APIs. While these datasets used various formats of time (e.g., minutes, hours, days), in order to integrate the datasets days format was used for in this research study. The integrated cryptocurrency historical datasets for 80 cryptocurrencies including but not limited to Bitcoin (BTC), Ethereum (ETH), Binance Coin (BNB), Cardano (ADA), Tether (USDT), Ripple (XRP), Solana (SOL), Polkadot (DOT), USD Coin (USDC), Dogecoin (DOGE), Tron (TRX), Bitcoin Cash (BCH), Litecoin (LTC), EOS (EOS), Cosmos (ATOM), Stellar (XLM), Wrapped Bitcoin (WBTC), Uniswap (UNI), Terra (LUNA), SHIBA INU (SHIB), and 60 more cryptocurrencies were uploaded in this online Mendeley data repository. Although the primary attribute of including the mentioned cryptocurrencies was the Market Capitalization, a subject matter expert i.e., a professional trader has also guided the initial selection of the cryptocurrencies by analyzing various indicators such as Relative Strength Index (RSI), Moving Average Convergence/Divergence (MACD), MYC Signals, Bollinger Bands, Fibonacci Retracement, Stochastic Oscillator and Ichimoku Cloud. The primary features of this dataset that were used as the decision-making criteria of the CLUS-MCDA II approach are Timestamps, Open, High, Low, Closed, Volume (Currency), % Change (7 days and 24 hours), Market Cap and Weighted Price values. The available excel and CSV files in this data set are just part of the integrated data and other databases, datasets and API References that was used in this study are as follows: [1] https://finance.yahoo.com/ [2] https://coinmarketcap.com/historical/ [3] https://cryptodatadownload.com/ [4] https://kaggle.com/philmohun/cryptocurrency-financial-data [5] https://kaggle.com/deepshah16/meme-cryptocurrency-historical-data [6] https://kaggle.com/sudalairajkumar/cryptocurrencypricehistory [7] https://min-api.cryptocompare.com/data/price?fsym=BTC&tsyms=USD [8] https://min-api.cryptocompare.com/ [9] https://p.nomics.com/cryptocurrency-bitcoin-api [10] https://www.coinapi.io/ [11] https://www.coingecko.com/en/api [12] https://cryptowat.ch/ [13] https://www.alphavantage.co/

Cryptocurrencies owned in the U.S. in 2023 were seemingly mainstream, with portfolios often consisting of Bitcoin (BTC), and Ethereum (ETH). To a certain degree, it might not be surprising to the ***** most-talked about virtual currencies of 2021 top this particular ranking. Differences, however, do show when one compares this list against the ownership of ** different cryptocurrencies in the United Kingdom. The order of the top owned digital coins are the same - albeit at a lower rate, except for Dogecoin (DOGE) and, interestingly, Ethereum (ETH). Indeed, respondents from Great Britain held relatively more coins - such as Ripple (XRP), Polkadot (DOT) and Cardano (ADA) - that were closely related to Ethereum. U.S. respondents were relatively more interested in Stellar (XLM) or the Basic Attention Token (BAT) than their British counterparts.
