Bitcoin has not solely been a trendsetter, ushering in a wave of cryptocurrencies constructed on a decentralized peer-to-peer community, but additionally has turn into the de facto commonplace for cryptocurrencies, inspiring an ever-growing legion of followers and spinoffs.
Key Takeaways
A cryptocurrency, broadly outlined, is a type of digital tokens or “coins” that exist on a distributed and decentralized ledger known as a blockchain.Beyond that, the sector of cryptocurrencies has expanded dramatically since Bitcoin was launched over a decade in the past, and the following nice digital token could also be launched tomorrow.Bitcoin continues to guide the pack of cryptocurrencies when it comes to market capitalization, person base, and recognition.Other digital currencies equivalent to Ethereum are getting used to create decentralized monetary (DeFi) methods.Some altcoins are being endorsed as having newer options than Bitcoin, equivalent to the power to deal with extra transactions per second or use completely different consensus algorithms like proof of stake.
What Are Cryptocurrencies?
Before we take a better have a look at a few of these options to Bitcoin, let’s step again and briefly look at what we imply by phrases like cryptocurrency and altcoin. A cryptocurrency, broadly outlined, is digital or digital cash that takes the type of tokens or “coins.” While some cryptocurrencies have ventured into the bodily world with bank cards or different tasks, the big majority stay fully intangible.
The “crypto” in cryptocurrencies refers to difficult cryptography that permits for the creation and processing of digital currencies and their transactions throughout decentralized methods. Alongside this necessary “crypto” function of those currencies is a typical dedication to decentralization; cryptocurrencies are sometimes developed as code by groups who construct in mechanisms for issuance (typically, though not all the time, by way of a course of known as mining) and different controls.
Cryptocurrencies are virtually all the time designed to be free from authorities manipulation and management—though, as they’ve grown extra fashionable, this foundational side of the trade has come beneath fireplace. The cryptocurrencies modeled after Bitcoin are collectively known as altcoins, and in some instances shitcoins, and have typically tried to current themselves as modified or improved variations of Bitcoin. While a few of these currencies might have some spectacular options that Bitcoin doesn’t, matching the extent of safety that Bitcoin’s networks obtain largely has but to be seen by an altcoin.
Below, we’ll look at a number of the most necessary digital currencies aside from Bitcoin. First, although, a caveat: It is not possible for an inventory like this to be fully complete. One cause for that is the truth that there are greater than 8,000 cryptocurrencies in existence as of December 2021. While many of those cryptos have little to no following or buying and selling quantity, some take pleasure in immense recognition amongst devoted communities of backers and traders.
Beyond that, the sector of cryptocurrencies is all the time increasing, and the following nice digital token could also be launched tomorrow. While Bitcoin is broadly seen as a pioneer on this planet of cryptocurrencies, analysts undertake many approaches for evaluating tokens aside from BTC. It’s frequent, as an example, for analysts to attribute a substantial amount of significance to rating cash relative to 1 one other when it comes to market capitalization. We’ve factored this into our consideration, however there are different the explanation why a digital token could also be included within the listing.
Types of Crypto
Cryptocurrencies are meant for use for funds, transmitting worth (akin to digital cash) throughout a decentralized community of customers. Many altcoins (i.e., not bitcoin or generally ether) are labeled on this method and will generally be known as worth tokens.
There are additionally blockchain-based tokens that should serve a distinct function from that of cash. One instance could possibly be a token issued as a part of an preliminary coin providing (ICO) that represents a stake in a blockchain or decentralized finance (DeFi) mission. If the tokens are linked to the worth of the corporate or mission, they are often known as safety tokens (as in securities like shares, not security).
Other tokens have a specific use case or perform. Examples embody Storj tokens, which permit individuals to share information throughout a decentralized community, or Namecoin, which supplies decentralized Domain Name System (DNS) service for Internet addresses. These are referred to as utility tokens.
Today, whereas many customers of crypto perceive and recognize these variations, merchants and lay traders might not discover the distinction, as all classes of token are inclined to commerce in the identical method on crypto exchanges.
1. Ethereum (ETH)
The first Bitcoin various on our listing, Ethereum, is a decentralized software program platform that allows good contracts and decentralized purposes (dApps) to be constructed and run with none downtime, fraud, management, or interference from a 3rd social gathering. The objective behind Ethereum is to create a decentralized suite of economic merchandise that anybody on this planet can freely entry, no matter nationality, ethnicity, or religion. This side makes the implications for these in some international locations extra compelling, as these with out state infrastructure and state identifications can get entry to financial institution accounts, loans, insurance coverage, or a wide range of different monetary merchandise.
The purposes on Ethereum are run on ether, its platform-specific cryptographic token. Ether (ETH) is sort of a automobile for shifting round on the Ethereum platform and is sought largely by builders seeking to develop and run purposes inside Ethereum, or now, by traders seeking to make purchases of different digital currencies utilizing ether. Ether, launched in 2015, is at present the second-largest digital foreign money by market capitalization after Bitcoin, though it lags behind the dominant cryptocurrency by a big margin. Trading at round $4,000 per ETH as of December 2021, ether’s market cap is simply over half that of bitcoin.
In 2014, Ethereum launched a presale for ether, which acquired an awesome response; this helped to usher within the age of the ICO. According to Ethereum, it may be used to “codify, decentralize, secure and trade just about anything.” Following the assault on the decentralized autonomous group (DAO) in 2016, Ethereum was break up into Ethereum (ETH) and Ethereum Classic (ETC).
In December 2020, Ethereum transitioned its consensus algorithm from proof of labor (PoW) to proof of stake (PoS). This transfer is meant to permit Ethereum’s community to run itself with far much less vitality and improved transaction pace, in addition to to make for a extra deflationary financial atmosphere. PoS permits community contributors to “stake” their ether to the community. This course of helps to safe the community and course of the transactions that happen. Those who do that are rewarded ether, just like an curiosity account. This is a substitute for Bitcoin’s PoW mechanism, the place miners are rewarded extra BTCs for processing transactions.
2. Litecoin (LTC)

Litecoin relies on an open-source international cost community that isn’t managed by any central authority and makes use of Scrypt as a PoW, which may be decoded with the assistance of consumer-grade central processing models (CPUs). Although Litecoin is like Bitcoin in some ways, it has a sooner block technology charge and therefore presents a sooner transaction affirmation time.
Other than builders, there are a rising variety of retailers that settle for Litecoin. As of December 2021, Litecoin has a market capitalization of $10 billion and a per-token worth of round $148, making it the 18th-largest cryptocurrency on this planet.
3. Cardano (ADA)
Cardano (ADA) is an “Ouroboros proof-of-stake” cryptocurrency that was created with a research-based method by engineers, mathematicians, and cryptography consultants.

After having some disagreements with the route that Ethereum was taking, he left and later helped to create Cardano.
The crew behind Cardano created its blockchain by way of in depth experimentation and peer-reviewed analysis. The researchers behind the mission have written greater than 120 papers on blockchain know-how throughout a variety of subjects. This analysis is the spine of Cardano.
Due to this rigorous course of, Cardano appears to face out amongst its PoS friends in addition to different massive cryptocurrencies. Cardano has additionally been dubbed the “Ethereum killer,” as its blockchain is alleged to be able to extra. That stated, Cardano continues to be in its early levels. While it has crushed Ethereum to the PoS consensus mannequin, it nonetheless has a protracted option to go when it comes to DeFi purposes.
Cardano goals to be the world’s monetary working system by establishing DeFi merchandise just like Ethereum in addition to offering options for chain interoperability, voter fraud, and authorized contract tracing, amongst different issues. As of December 2021, Cardano has the sixth-largest market capitalization at $42 billion, and one ADA trades for round $1.25.
4. Polkadot (DOT)
Polkadot (DOT) is a novel PoS cryptocurrency geared toward delivering interoperability amongst different blockchains. Its protocol is designed to attach permissioned and permissionless blockchains, in addition to oracles, to permit methods to work collectively beneath one roof. Polkadot’s core element is its relay chain that permits the interoperability of various networks. It additionally permits for parachains, or parallel blockchains with their very own native tokens for specific-use instances.
Where Polkadot differs from Ethereum is that moderately than creating simply dApps on Polkadot, builders can create their very own blockchain whereas additionally utilizing the safety that Polkadot’s chain already has. With Ethereum, builders can create new blockchains however have to create their very own safety measures, which might go away new and smaller tasks open to assault, because the bigger a blockchain, the extra safety it has. This idea in Polkadot is named shared safety.
Polkadot was created by Gavin Wood, one other member of the core founders of the Ethereum mission who had differing opinions on the mission’s future. As of December 2021, Polkadot has a market capitalization of roughly $25 billion and one DOT trades for $25.
5. Bitcoin Cash (BCH)
Bitcoin Cash (BCH) holds an necessary place within the historical past of altcoins as a result of it is without doubt one of the earliest and most profitable exhausting forks of the unique Bitcoin. In the cryptocurrency world, a fork takes place as the results of debates and arguments between builders and miners. Due to the decentralized nature of digital currencies, wholesale modifications to the code underlying the token or coin at hand should be made resulting from basic consensus; the mechanism for this course of varies in accordance with the actual cryptocurrency.
When completely different factions can’t agree, generally the digital foreign money is break up, with the unique chain remaining true to its authentic code and the brand new chain starting life as a brand new model of the prior coin, full with modifications to its code.
BCH started its life in August 2017 on account of one in every of these splits. The debate that led to the creation of BCH needed to do with the problem of scalability; the Bitcoin community has a restrict on the dimensions of blocks: one megabyte (MB). BCH will increase the block dimension from one MB to eight MBs, with the thought being that bigger blocks can maintain extra transactions inside them, and the transaction pace due to this fact can be elevated. It additionally makes different modifications, together with the elimination of the Segregated Witness protocol that impacts block area.
As of December 2021, BCH has a market capitalization of round $8.2 billion and a worth per token of $436.

Binance Coin’s blockchain can be the platform that Binance’s decentralized change operates on. The Binance Exchange was based by Changpeng Zhao and is without doubt one of the most generally used exchanges on this planet primarily based on buying and selling volumes.
Binance Coin was initially an ERC-20 token that operated on the Ethereum blockchain. It finally had its personal mainnet launch. The community makes use of a PoS consensus mannequin. As of November 2021, Binance Coin has a $91.5 billion market capitalization, with one BNB having a worth of $545.
9. Tether (USDT)
Tether (USDT) was one of many first and hottest of a gaggle of so-called stablecoins—cryptocurrencies that goal to peg their market worth to a foreign money or different exterior reference level to scale back volatility. Because most digital currencies, even main ones like Bitcoin, have skilled frequent durations of dramatic volatility, Tether and different stablecoins try and clean out worth fluctuations to draw customers who might in any other case be cautious. Tether’s worth is tied on to the value of the U.S. greenback. The system permits customers to extra simply make transfers from different cryptocurrencies again to U.S. {dollars} in a extra well timed method than really changing to regular foreign money.
