A cryptocurrency, broadly defined, is currency that takes the form of tokens or “coins” and exists on a distributed and decentralized ledger.
Beyond that, the field of cryptocurrencies has expanded dramatically since Bitcoin was launched over a decade ago, and the next great digital token may be released tomorrow.
Bitcoin continues to lead the pack of cryptocurrencies in terms of market capitalization, user base, and popularity.
Other virtual currencies such as Ethereum are being used to create decentralized financial systems for those without access to traditional financial products.
Some altcoins are being endorsed as they have newer features than Bitcoin, such as the ability to handle more transactions per second or use different consensus algorithms like proof-of-stake.
Cardano (ADA)
Cardano is an “Ouroboros proof-of-stake” cryptocurrency that was created with a research-based approach by engineers, mathematicians, and cryptography experts. The project was co-founded by Charles Hoskinson, one of the five initial founding members of Ethereum. After having some disagreements with the direction Ethereum was taking, he left and later helped to create Cardano.
The team behind Cardano created its blockchain through extensive experimentation and peer-reviewed research. The researchers behind the project have written over 90 papers on blockchain technology across a range of topics. This research is the backbone of Cardano.
Due to this rigorous process, Cardano seems to stand out among its proof-of-stake peers as well as other large cryptocurrencies. Cardano has also been dubbed the “Ethereum killer” as its blockchain is said to be capable of more. That said, Cardano is still in its early stages. While it has beaten Ethereum to the proof-of-stake consensus model it still has a long way to go in terms of decentralized financial applications.
Polkadot (DOT)
Polkadot is a unique proof-of-stake cryptocurrency that is aimed at delivering interoperability between other blockchains. Its protocol is designed to connect permissioned and permissionless blockchains as well as oracles to allow systems to work together under one roof.
Polkadot’s core component is its relay chain that allows the interoperability of varying networks. It also allows for “parachains,” or parallel blockchains with their own native tokens for specific use cases.
Binance Coin (BNB)
Binance Coin is a utility cryptocurrency that operates as a payment method for the fees associated with trading on the Binance Exchange. Those who use the token as a means of payment for the exchange can trade at a discount. Binance Coin’s blockchain is also the platform that Binance’s decentralized exchange operates on. The Binance exchange was founded by Changpeng Zhao and the exchange is one of the most widely used exchanges in the world based on trading volumes.
Tether (USDT)
Tether was one of the first and most popular of a group of so-called stablecoins, cryptocurrencies that aim to peg their market value to a currency or other external reference point in order to reduce volatility. Because most digital currencies, even major ones like Bitcoin, have experienced frequent periods of dramatic volatility, Tether and other stablecoins attempt to smooth out price fluctuations in order to attract users who may otherwise be cautious. Tether’s price is tied directly to the price of the US dollar. The system allows users to more easily make transfers from other cryptocurrencies back to US dollars in a more timely manner than actually converting to normal currency.
Monero (XMR)
Monero is a secure, private, and untraceable currency. This open-source cryptocurrency was launched in April 2014 and soon garnered great interest among the cryptography community and enthusiasts. The development of this cryptocurrency is completely donation based and community driven. Monero has been launched with a strong focus on decentralization and scalability, and it enables complete privacy by using a special technique called “ring signatures.”
With this technique, there appears a group of cryptographic signatures including at least one real participant, but since they all appear valid, the real one cannot be isolated. Because of exceptional security mechanisms like this, Monero has developed something of an unsavory reputation—it has been linked to criminal operations around the world. While this is a prime candidate for making criminal transactions anonymously, the privacy inherent in Monero is also helpful to dissidents of oppressive regimes around the world. As of January 2021, Monero had a market cap of $2.8 billion and a per-token value of $158.37.
