What are the most popular cryptocurrencies?

The most popular cryptocurrencies:

• Despite its considerable volatility over the course of its history, Bitcoin (BTC) remains the most popular and highly valuable cryptocurrency. Bitcoin was founded with the intention of being used as a digital payment system, but experts believe it is still too volatile for that.
• Ether (ETH) is the Ethereum network's money, an open-source blockchain on which developers can create apps and other cryptocurrencies. It's also the second most valuable cryptocurrency in terms of market capitalization, after Bitcoin. Since its inception in 2013, Ether's value has climbed dramatically, reaching about $3,000 per token in late May, but it still behind Bitcoin's worth of nearly $40,000 per coin.
• The Ripple digital payment network's cryptocurrency is called XRP. XRP, which was created for digital payments, claims to be a faster and more efficient way to enable global payments. Third-party work on alternative uses for XRP is also possible with Ripple and XRP.
• Tether (USDT) is a stablecoin that is linked to a fiat currency, in this case the US dollar. Tether is the most valuable stablecoin in terms of market capitalization.
• Cardano (ADA) is based on the Ouroboros blockchain platform, which has been peer-reviewed. It bills itself as a more secure and scalable way to keep decentralisation alive.
