The best cryptocurrency (2021)
What Is a Cryptocurrency?
A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on blockchain technology — a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.
- A cryptocurrency is a new form of digital asset based on a network that is distributed across a large number of computers. This decentralized structure allows them to exist outside the control of governments and central authorities.
- The word “cryptocurrency” is derived from the encryption techniques which are used to secure the network.
- Blockchains, which are organizational methods for ensuring the integrity of transactional data, is an essential component of many cryptocurrencies.
- Many experts believe that blockchain and related technology will disrupt many industries, including finance and law.
- Cryptocurrencies face criticism for a number of reasons, including their use for illegal activities, exchange rate volatility, and vulnerabilities of the infrastructure underlying them. However, they also have been praised for their portability, divisibility, inflation resistance, and transparency.
Cryptocurrencies are systems that allow for secure payments online which are denominated in terms of virtual “tokens,” which are represented by ledger entries internal to the system. “Crypto” refers to the various encryption algorithms and cryptographic techniques that safeguard these entries, such as elliptical curve encryption, public-private key pairs, and hashing functions.
Types of Cryptocurrency
Some of the competing cryptocurrencies spawned by Bitcoin’s success, known as “altcoins,” include Litecoin, Peercoin, and Name coin, as well as Ethereum, Cardano, and EOS. Today, the aggregate value of all the cryptocurrencies in existence is around $214 billion — Bitcoin currently represents more than 68% of the total value.
Some of the cryptography used in cryptocurrency today was originally developed for military applications. At one point, the government wanted to put controls on cryptography similar to the legal restrictions on weapons, but the right for civilians to use cryptography was secured on grounds of freedom of speech.
Central to the appeal and functionality of Bitcoin and other cryptocurrencies is block chain technology, which is used to keep an online ledger of all the transactions that have ever been conducted, thus providing a data structure for this ledger that is quite secure and is shared and agreed upon by the entire network of individual node, or computer maintaining a copy of the ledger. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories.
Many experts see blockchain technology as having serious potential for uses like online voting and crowdfunding, and major financial institutions such as JPMorgan Chase (JPM) see the potential to lower transaction costs by streamlining payment processing.4 However, because cryptocurrencies are virtual and are not stored on a central database, a digital cryptocurrency balance can be wiped out by the loss or destruction of a hard drive if a backup copy of the private key does not exist. At the same time, there is no central authority, government, or corporation that has access to your funds or your personal information.
Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties, without the need for a trusted third party like a bank or credit card company. These transfers are instead secured by the use of public keys and private keys and different forms of incentive systems, like Proof of Work or Proof of Stake.
In modern cryptocurrency systems, a user’s “wallet,” or account address, has a public key, while the private key is known only to the owner and is used to sign transactions. Fund transfers are completed with minimal processing fees, allowing users to avoid the steep fees charged by banks and financial institutions for wire transfers.
Criticism of Cryptocurrency
Since market prices for cryptocurrencies are based on supply and demand, the rate at which a cryptocurrency can be exchanged for another currency can fluctuate widely, since the design of many cryptocurrencies ensures a high degree of scarcity.
Bitcoin has experienced some rapid surges and collapses in value, climbing as high as $19,000 per Bitcoin in Dec. of 2017 before dropping to around $7,000 in the following months.2 Cryptocurrencies are thus considered by some economists to be a short-lived fad or speculative bubble.
There is concern that cryptocurrencies like Bitcoin are not rooted in any material goods. Some research, however, has identified that the cost of producing a Bitcoin, which requires an increasingly large amount of energy, is directly related to its market price.
Cryptocurrency blockchains are highly secure, but other aspects of a cryptocurrency ecosystem, including exchanges and wallets, are not immune to the threat of hacking. In Bitcoin’s 10-year history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars worth of “coins” stolen.
Nonetheless, many observers see potential advantages in cryptocurrencies, like the possibility of preserving value against inflation and facilitating exchange while being easier to transport and divide than precious metals and existing outside the influence of central banks and governments.

What is the Best Cryptocurrency?
The most daring investors can purchase new cryptocurrencies at the initial coin offering or shortly thereafter, following the example set by many of today’s Bitcoin millionaires. However, there may never be a “next Bitcoin”, and the estimated 1,000 cryptocurrencies that have vanished into the digital ether point to risks for early investors. Take a look at which coins made the list.
1. Bitcoin (BTC)
2. Ethereum (ETH)
3. Ripple (XRP)
4. EOS (EOS)
5. Bitcoin Cash (BCH)
6. Litecoin (LTC)
Final Thoughts on Best Cryptocurrencies
Cryptocurrencies are still in their formative years. If you’re new to cryptocurrencies, you may be better served by investing only risk capital and by building a portfolio of widely traded cryptocurrencies. Initial coin offerings can be tempting, particularly with the parabolic rises common to ICOs. Almost as common is a precipitous fall following the ICO.
More established currencies help to prevent some of the volatility and provide better liquidity than found with newly minted cryptocurrencies. It’s important to learn where a cryptocurrency can be traded and how big the market is for that cryptocurrency.
Many early investors have found themselves without a viable way to exit the position. If cryptocurrencies are here to stay, some very good opportunities are likely to exist among the most commonly traded currencies, while also minimizing risk due to abandoned projects or lack of liquidity.
