Do all cryptocurrencies use blockchain
The very first cryptocurrency was Bitcoin. Since it is open source, it is possible for other people to use the majority of the code, make a few changes and then launch their own separate currency Caesar’s online casino. Many people have done exactly this. Some of these coins are very similar to Bitcoin, with just one or two amended features (such as Litecoin), while others are very different, with varying models of security, issuance and governance. However, they all share the same moniker — every coin issued after Bitcoin is considered to be an altcoin.
Cryptocurrency was invented by Satoshi Nakamoto, which is the pseudonym used by the inventor of Bitcoin. Even though digital currency concepts existed before Bitcoin, Satoshi Nakamoto was the first to create a peer-to-peer digital currency that reliably solved the issues facing previous digital money projects. Bitcoin was initially proposed in 2008 and launched in early 2009. Following the invention of Bitcoin, thousands of projects have attempted to imitate Bitcoin’s success or improve upon the original Bitcoin design by leveraging new technologies.
A distributed ledger is a database with no central administrator that is maintained by a network of nodes. In permissionless distributed ledgers, anyone is able to join the network and operate a node. In permissioned distributed ledgers, the ability to operate a node is reserved for a pre-approved group of entities.

Additionally, reconciliation processes are undergoing a transformation. Aaron Holmes of Kani Payments highlights the inefficiencies of manual reconciliation, with many businesses still relying on spreadsheets. Advanced reconciliation tools are expected to save time, improve accuracy, and enable scalable growth.
There are use cases where cards make perfect sense. But there are also moments, especially for larger ticket purchases or recurring payments, where direct bank transfers or account-based payments create more value.
Contactless payments have seen a significant surge in adoption, particularly accelerated by the COVID-19 pandemic. Consumers and businesses alike have embraced the convenience and safety of contactless transactions. This trend shows no signs of slowing down. According to a study by Juniper Research, the value of contactless payments is expected to reach $10 trillion globally by 2027. This growth is driven by advancements in Near Field Communication (NFC) technology and the increasing availability of contactless payment terminals.

Market cap of all cryptocurrencies
Price volatility has long been one of the features of the cryptocurrency market. When asset prices move quickly in either direction and the market itself is relatively thin, it can sometimes be difficult to conduct transactions as might be needed. To overcome this problem, a new type of cryptocurrency tied in value to existing currencies — ranging from the U.S. dollar, other fiats or even other cryptocurrencies — arose. These new cryptocurrency are known as stablecoins, and they can be used for a multitude of purposes due to their stability.
Crypto market capitalization or “crypto market cap” for short is a widely used metric that is commonly used to compare the relative size of different cryptocurrencies. On CoinCodex, market cap is the default metric by which we rank cryptocurrencies on our frontpage. We also track the total cryptocurrency market cap by adding together the market cap of all the cryptocurrencies listed on CoinCodex. The total market cap provides an estimate on whether the cryptocurrency market as a whole is growing or declining.
Crypto prices are calculated by averaging cryptocurrency exchange rates on different cryptocurrency trading platforms. This way, we can determine an average price that reflects cryptocurrency market conditions as accurately as possible.
Why do all cryptocurrencies rise and fall together
Since very few commercial outlets and entities worldwide accept cryptocurrencies for typical purchases, they tend to trade more like speculative assets than traditional fiat currencies that have state backing and widespread commercial use cases.
One of the most common beginner questions regarding cryptocurrencies is, “Why does crypto go up and down?” This question is another way of asking how the value of cryptocurrencies is determined, and the answer is supply and demand.
However, the inverse is also true. When crypto markets are going down, it is typically because specific coins have lost market perception due to negative events, such as bad publicity, unethical behavior from project leaders, or security breaches.
First of all, cryptocurrencies are unregulated assets. That means that central authorities, such as banks and regulatory authorities can’t affect cryptocurrencies in the same way as they usually can with regular currencies and assets. See the stock market for instance – here, central authorities can regulate the price of assets with the purpose of stabilising the price. But that’s not a possibility with cryptocurrencies, as cryptocurrencies are decentralised currencies. Read more about the meaning of decentralised in our blog post “What is cryptocurrency?”.
These psychological factors contribute to market volatility. Investors who act impulsively often face negative outcomes, especially during periods of extreme price fluctuations. Understanding these dynamics can help investors make more informed decisions and avoid falling victim to emotional trading.
