What is cryptocurrency
The circulating supply of a cryptocurrency is the amount of units that is currently available for use. Let’s use Bitcoin as an example. There is a rule in the Bitcoin code which says that only 21 million Bitcoins can ever be created how do nascar races work. The circulating supply of Bitcoin started off at 0 but immediately started growing as new blocks were mined and new BTC coins were being created to reward the miners. Currently, there are around 19.87 million Bitcoins in existence, and this number will keep growing until the 21 millionth BTC is mined. Since 19.87 million BTC have been mined so far, we say that this is the circulating supply of Bitcoin.
Almost. We have a process that we use to verify assets. Once verified, we create a coin description page like this. The world of crypto now contains many coins and tokens that we feel unable to verify. In those situations, our Dexscan product lists them automatically by taking on-chain data for newly created smart contracts. We do not cover every chain, but at the time of writing we track the top 70 crypto chains, which means that we list more than 97% of all tokens.
A stablecoin is a crypto asset that maintains a stable value regardless of market conditions. This is most commonly achieved by pegging the stablecoin to a specific fiat currency such as the US dollar. Stablecoins are useful because they can still be transacted on blockchain networks while avoiding the price volatility of “normal” cryptocurrencies such as Bitcoin and Ethereum. Outside of stablecoins, cryptocurrency prices can change rapidly, and it’s not uncommon to see the crypto market gain or lose more than 10% in a single day.
CoinCodex provides all the data you need to stay informed about cryptocurrencies. You can find cryptocurrency charts for more than 41492 coins, and access key data such as up-to-date prices, all-time high price, cryptocurrency market cap, trading volume and more. The crypto charts provided by CoinCodex are incredibly flexible – you can watch real-time prices or select between 8 pre-defined time frames, ranging from 24 hours to the entire price history of the coin. If you need more precision, you can select a custom date range. CoinCodex also gives you the ability to compare the price action of different cryptocurrencies on a single chart.

The current value, not the long-term value, of the cryptocurrency supports the reward scheme to incentivize miners to engage in costly mining activities. In 2018, bitcoin’s design caused a 1.4% welfare loss compared to an efficient cash system, while a cash system with 2% money growth has a minor 0.003% welfare cost. The main source for this inefficiency is the large mining cost, which is estimated to be US$360 million per year. This translates into users being willing to accept a cash system with an inflation rate of 230% before being better off using bitcoin as a means of payment. However, the efficiency of the bitcoin system can be significantly improved by optimizing the rate of coin creation and minimizing transaction fees. Another potential improvement is to eliminate inefficient mining activities by changing the consensus protocol altogether.
DeFi tokens are the backbone of decentralized finance (DeFi) applications. They allow users to lend cryptocurrencies and earn interest or borrow against them. For instance, the Ethereum-based lending platform Compound’s (COMP) token is a DeFi token that is used for these purposes.
Some miners pool resources, sharing their processing power over a network to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A “share” is awarded to members of the mining pool who present a valid partial proof-of-work.
The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. At least one study has shown that broad generalizations about the use of bitcoin in illicit finance are significantly overstated and that blockchain analysis is an effective crime fighting and intelligence gathering tool. While some countries have explicitly allowed their use and trade, others have banned or restricted it. According to the Library of Congress in 2021, an “absolute ban” on trading or using cryptocurrencies applies in 9 countries: Algeria, Bangladesh, Bolivia, China, Egypt, Iraq, Morocco, Nepal, and the United Arab Emirates. An “implicit ban” applies in another 39 countries or regions, which include: Bahrain, Benin, Burkina Faso, Burundi, Cameroon, Chad, Cote d’Ivoire, the Dominican Republic, Ecuador, Gabon, Georgia, Guyana, Indonesia, Iran, Jordan, Kazakhstan, Kuwait, Lebanon, Lesotho, Macau, Maldives, Mali, Moldova, Namibia, Niger, Nigeria, Oman, Pakistan, Palau, Republic of Congo, Saudi Arabia, Senegal, Tajikistan, Tanzania, Togo, Turkey, Turkmenistan, Qatar and Vietnam. In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating “Bitcoin scams” and ICOs in 40 jurisdictions.
According to the European Central Bank, the decentralization of money offered by bitcoin has its theoretical roots in the Austrian school of economics, especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined, in which Hayek advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.

A cryptocurrency is a decentralized digital currency. It’s called cryptocurrency because all transactions are protected by cryptography. However, the revolutionary with cryptocurrencies is the blockchain technology. This makes them completely decentralized. In other words, there is no bank, company or intermediary. By removing all middlemen you avoid expensive fees, long waiting times and the need to trust a third party. With cryptocurrency, you send money faster, cheaper and easier.
Bitcoin’s price has skyrocketed as it’s become a household name. In May 2016, you could buy one bitcoin for about $500. As of Apr. 29, 2025, a single bitcoin’s price was around $83,664. That’s a growth of 12,668%.
Like Tether, USD Coin (USDC) is a stablecoin, meaning it’s backed by U.S. dollars and aims for a 1 USD to 1 USDC ratio. USDC is powered by Ethereum, and you can use USD Coin to complete global transactions.
There are over 10,000 cryptocurrencies on the market today. It’s hard to keep track of all of them! On this page, you will find all cryptocurrencies with price graphs updated in real time. It’s easy to compare market capitalization, volume, supply and more between cryptocurrencies. Do you want to see prices in dollar (USD), euro (EUR), pounds (GBP) or any other currency?

As 2022’s crypto crash demonstrated, the crypto market is volatile and unpredictable. Trading is a popular short-term crypto investment strategy that requires you to buy and sell based on when you expect prices to increase or decrease. Many short-term traders watch average prices over a period to get a feel for how they’re trending. Having technical analysis skills, which use past patterns and prices for the crypto investment you’re considering, is an essential skill to master.
Cryptocurrencies are fungible, meaning the value remains the same when bought, sold, or traded. It is not the same as non-fungible tokens (NFTs), which have fluctuating values dependent on many variables, such as the digital asset it’s attached to. The market capitalization of crypto depends on the number of coins in circulation. Although the cryptocurrency market is not heavily regulated by the US government, they are taxable assets. You’ll need to file any profit or loss with the Internal Revenue Service (IRS).
Cryptocurrencies have become a popular tool with criminals for nefarious activities such as money laundering and illicit purchases. The case of Dread Pirate Roberts, who ran a marketplace to sell drugs on the dark web, is already well known. Cryptocurrencies have also become a favorite of hackers who use them for ransomware activities.
South Africa, which has seen a large number of scams related to cryptocurrency, is said to be putting a regulatory timeline in place that will produce a regulatory framework. The largest scam occurred in April 2021, where the two founders of an African-based cryptocurrency exchange called Africrypt, Raees Cajee and Ameer Cajee, disappeared with $3.8 billion worth of bitcoin. Additionally, Mirror Trading International disappeared with $170 million worth of cryptocurrency in January 2021.
The rewards paid to miners increase the supply of the cryptocurrency. By making sure that verifying transactions is a costly business, the integrity of the network can be preserved as long as benevolent nodes control a majority of computing power. The verification algorithm requires a lot of processing power, and thus electricity, in order to make verification costly enough to accurately validate the public blockchain. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, they must further consider the significant amount of electrical power in search of the solution. Generally, the block rewards outweigh electricity and equipment costs, but this may not always be the case.
