A summary of data sources for reviewing different crypto-exchanges

Types of sources	Description
Startup and technology news reporting websites	These websites discussed the development and successes of different FinTech and cryptocurrency firms. Examples included Coindesk.com, G2.com, businesswire.com and TechCrunch.com. Some URLs of the web pages that we checked are as follows https://www.coindesk.com/policy/2022/02/08/coinbase-files-to-form-a-pac-ahead-of-2022-midterms https://www.businesswire.com/news/home/20151014005723/en/Bitreserve-Now-Uphold-Integrates-with-the-Global-Financial-Ecosystem
Online review portals of technological services	Customers of technological services, including crypto-exchanges, often share comments and insights. These inputs can reveal their successes, how they achieved the necessary attributes and hint at whether we should include them in our data collection. Sources of these comments and insights include G2.com, Finder.com.au and Coindesk.com. More specifically, some URLs of the web pages that we checked are as follows G2's review on Uphold: https://www.g2.com/products/uphold/reviews G2's review on Binance: https://www.g2.com/products/binance/reviews Finder's review on Coinbase: https://www.finder.com.au/cryptocurrency/exchanges/coinbase-exchange-review Finder's review on Kraken: https://www.finder.com.au/cryptocurrency/exchanges/kraken-exchange-review Given the proliferation of “internet-water-army”, which were paid to manipulate the public sentiment or eWOM of different firms, we checked carefully on the identity of the Internet users who left the comments or reviews, possibly via the review verification mechanism of the review portals. For example, if the Internet users had no other (or very limited) comments on the same portals or websites, or if all of his/her comments were largely related to only a few crypto-exchanges, we would not include them in our dataset.
External online communities	Online cryptocurrency-related forums indicated user viewpoints on different crypto-exchanges and trends. Interactions among forum members were analysed alongside online reviews, revealing additional facets of these services. Some of the related links are as follows Reddit's cryptocurrency broad (non-specific to any firms or cryptocurrencies): https://www.reddit.com/r/CryptoCurrency/?rdt=56929 Reddit's Coinbase broad: https://www.reddit.com/r/CoinBase/ Bitcoin Forum: https://bitcointalk.org/ Akin to handling data from online review portals, similar measures have been taken to eliminate the comments from “internet-water-army”.
Official blogs and websites	Some exchanges have their own blogs (e.g. Uphold, Coinbase and Binance). These provided information on their updates and senior executives' insights. Some of the website URLs are as follows Binance: https://www.binance.com Uphold.com: https://www.uphold.com Gemini: https://www.gemini.com/ KuCoin Blog: https://www.kucoin.com/blog
