Dogecoin Was Up More Than 10% Today. Should You Buy?
Bitcoin has not only been a trendsetter, ushering in a wave of cryptocurrencies built on a decentralized peer-to-peer network, but has also become the de facto standard for cryptocurrencies, inspiring an ever-growing legion of followers and spinoffs. Cryptocurrencies are almost always designed to be free from government manipulation and control—although, as they have grown more popular, this foundational aspect of the industry has come under fire.
The cryptocurrencies modeled after Bitcoin are collectively called altcoins, and in some cases, shitcoins , and have often tried to present themselves as modified or improved versions of Bitcoin. First, though, a caveat: It is impossible for a list like this to be entirely comprehensive. One reason for this is the fact that there are more than 8, cryptocurrencies in existence as of January Though many of these cryptos have little to no following or trading volume, some enjoy immense popularity among dedicated communities of backers and investors.
Beyond that, the field of cryptocurrencies is always expanding, and the next great digital token may be released tomorrow. Though Bitcoin is widely seen as a pioneer in the world of cryptocurrencies, analysts adopt many approaches for evaluating tokens other than BTC.
Cryptocurrencies are intended for payments, transmitting value akin to digital money across a decentralized network of users.
Many altcoins i. There are also blockchain-based tokens that are meant to serve a different purpose from that of money. One example could be a token issued as part of an initial coin offering ICO that represents a stake in a blockchain or decentralized finance DeFi project. If the tokens are linked to the value of the company or project, they can be called security tokens as in securities like stocks, not safety.
Other tokens have a particular use case or function. Examples include Storj tokens, which allow people to share files across a decentralized network, or Namecoin, which provides decentralized Domain Name System DNS service for Internet addresses.
These are known as utility tokens. Today, while many users of crypto understand and appreciate these differences, traders and lay investors may not notice the difference because all categories of token tend to trade on crypto exchanges in the same way.
The first Bitcoin alternative on our list, Ethereum ETH , is a decentralized software platform that enables smart contracts and decentralized applications dApps to be built and run without any downtime, fraud, control, or interference from a third party. The goal behind Ethereum is to create a decentralized suite of financial products that anyone in the world can freely access, regardless of nationality, ethnicity, or faith.
This aspect makes the implications for those in some countries more compelling because those without state infrastructure and state identifications can get access to bank accounts, loans, insurance, or a variety of other financial products.
The applications on Ethereum are run on ether, its platform-specific cryptographic token. Ether ETH is like a vehicle for moving around on the Ethereum platform and is sought mostly by developers looking to develop and run applications inside Ethereum, or now, by investors looking to make purchases of other digital currencies using ether.
Ether, launched in , is currently the second-largest digital currency by market capitalization after Bitcoin, although it lags behind the dominant cryptocurrency by a significant margin. In , Ethereum launched a presale for ether, which received an overwhelming response; this helped to usher in the age of the ICO.
This process helps to secure the network and process the transactions that occur. Those who do this are rewarded with ether, similarly to how an interest account works. Litecoin is based on an open-source global payment network that is not controlled by any central authority and uses scrypt as a PoW, which can be decoded with the help of consumer-grade central processing units CPUs.
Although Litecoin is like Bitcoin in many ways, it has a faster block generation rate and thus offers a faster transaction confirmation time. Other than developers, there are a growing number of merchants that accept Litecoin. The project was co-founded by Charles Hoskinson, one of the five initial founding members of Ethereum. After having some disagreements with the direction that 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 more than 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 PoS peers as well as other large cryptocurrencies. That said, Cardano is still in its early stages. Though it has beaten Ethereum to the PoS consensus model, it still has a long way to go in terms of DeFi applications. Polkadot DOT is a unique PoS cryptocurrency aimed at delivering interoperability among 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.
It also allows for parachains, or parallel blockchains with their own native tokens for specific-use cases. With Ethereum, developers can create new blockchains but need to create their own security measures, which can leave new and smaller projects open to attack because the larger a blockchain, the more security it has.
This concept in Polkadot is known as shared security. Bitcoin Cash BCH holds an important place in the history of altcoins because it is one of the earliest and most successful hard forks of the original Bitcoin. In the cryptocurrency world, a fork takes place as the result of debates and arguments between developers and miners.
Due to the decentralized nature of digital currencies, wholesale changes to the code underlying the token or coin at hand must be made due to general consensus; the mechanism for this process varies according to the particular cryptocurrency. BCH began its life in August as a result of one of these splits. The debate that led to the creation of BCH had to do with the issue of scalability; the Bitcoin network has a limit on the size of blocks: 1 megabyte MB. BCH increases the block size from 1MB to 8MBs, with the idea being that larger blocks can hold more transactions within them, and the transaction speed would therefore increase.
It also makes other changes, including the removal of the Segregated Witness protocol that impacts block space. Stellar XLM is an open blockchain network designed to provide enterprise solutions by connecting financial institutions for the purpose of large transactions.
Huge transactions between banks and investment firms—typically taking several days, involving a number of intermediaries, and costing a good deal of money—can now be made nearly instantaneously with no intermediaries and cost little to nothing for those making the transaction. Though Stellar has positioned itself as an enterprise blockchain for institutional transactions, it is still an open blockchain that anyone can use.
The system allows for cross-border transactions among any currency. The network requires users to hold Lumens to be able to transact on the network. He eventually left his role with Ripple and went on to co-found the Stellar Development Foundation.
The coin, which uses an image of the Shiba Inu as its avatar, is accepted as a form of payment by some major companies, including the Dallas Mavericks, Kronos, and—perhaps most notably—SpaceX, an American aerospace manufacturer owned by Elon Musk.
Dogecoin was created by two software engineers, Billy Markus and Jackson Palmer, in Markus and Palmer reportedly created the coin as a joke, commenting on the wild speculation of the cryptocurrency market. A memecoin inspired by a memecoin, Shiba Inu SHIB , rose to prominence in the fall of , briefly surpassing the market capitalization of Dogecoin.
Binance Coin BNB is a utility cryptocurrency that operates as a payment method for the fees associated with trading on the Binance Exchange. It is the third-largest cryptocurrency by market capitalization. Those who use the token as a means of payment for the exchange can trade at a discount. The Binance Exchange was founded by Changpeng Zhao and is one of the most widely used exchanges in the world based on trading volumes.
It eventually had its own mainnet launch. The network uses a PoS consensus model. Tether USDT 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 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 to attract users who may otherwise be cautious. The system allows users to more easily make transfers from other cryptocurrencies back to U.
Monero XMR is a secure, private, and untraceable currency. This open-source cryptocurrency was launched in April and soon garnered great interest among the cryptography community and its enthusiasts. The development of this cryptocurrency is completely donation-based and community-driven.
Because of these exceptional security mechanisms, Monero has developed something of an unsavory reputation—it has been linked to criminal operations around the world.
As decentralized platforms, blockchain-based cryptocurrencies allow individuals to engage in peer-to-peer financial transactions or enter into contracts. In either case, there is no need for some trusted third-party intermediary such as a bank, monetary authority, court, or judge.
This has the potential to disrupt the existing financial order and democratize finance. The majority of cryptocurrencies today are derived in some form or another from Bitcoin, which uses open-source code and a censorship-resistant architecture.
This means that anybody can copy and tweak the code and create their own new coin. This also means that anybody is free to join its network or transact in it.
Many cryptocurrencies have gained importance or hold the promise to do so. Dogecoin, for example, was a meme-based joke coin that reached fame when Tesla CEO Elon Musk promoted the token on social media. Despite thousands of competitors that have sprung up, Bitcoin—the original cryptocurrency—remains the dominant player in terms of usage and economic value. Investing in cryptocurrencies and other initial coin offerings ICOs is highly risky and speculative, and this article is not a recommendation by Investopedia or the writer to invest in cryptocurrencies or other ICOs.

The total market value of a cryptocurrency's circulating supply. It is analogous to the free-float capitalization in the stock market. The amount of coins that are circulating in the market and are in public hands. It is analogous to the flowing shares in the stock market. It includes coins that have been already created, minus any coins that have been burned. This is the ranking of a coin based on MCap or Market capitalization. Higher the market capitalization of a company, higher the rank it is assigned.

Bitcoin and other cryptocurrencies crashed further on Wednesday, after Chinese regulators stepped up efforts to crack down on financial institutions offering crypto services. Other coins suffered similar losses. The move comes as China gears up to launch its own digital currency. Many see the crackdown on existing cryptocurrencies as an attempt to limit competition. The Chinese Government is planning to create a digital renminbi, which would allow the central bank to track all transactions as they happen.

View All. By creating a distributed network of ledgers that work together to keep all transactions, contracts and accounts public, they eliminate the need for mediation to large extent via a concept named as Proof of work. Proof of work is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions the so-called block on a distributed ledger called blockchain. Bitcoin has a cryptographic security feature to ensure that only the owner of a Bitcoin can spend it. The idea is that the owner generates two numbers—a private key that is secret and a public key that is published. The public key can be easily generated from the private key, but not vice versa. A signature can be used to verify that the owner holds the private key, without revealing the private key, using a technique known as an elliptic curve signature scheme.
The past year-plus has seen a fresh explosion in cryptocurrencies. Companies are enabling payments via these digital assets or embracing the blockchain technology behind Bitcoin and others, creating a boon for some of the biggest cryptocurrencies. It's all part of what has become known as DeFi, or decentralized finance.
