What is cryptocurrency
Since Nakamoto’s first Bitcoin block, thousands of developers have introduced improvements to Bitcoin’s code. And over the past decade, Bitcoin has risen in popularity as a digital asset class, with more people, companies, and even countries accepting its usage or maintaining Bitcoin funds in their balance sheets casino documentary.
Nakamoto created the first Bitcoin on January 3, 2009. Bitcoin was initially mined among tech enthusiasts until the first trading markets for Bitcoin emerged in July 2010, with prices then ranging from US$0.0008 and $0.08. By then, Nakamoto transferred Bitcoin’s network alert key and control of the code repository to Gavin Andresen, who became lead developer at the Bitcoin Foundation.
The live Bitcoin price today is $103,466.90 as of 5/14/2025, with a 24-hour trading volume of $30,278,706,301. Bitcoin’s price is up 0.95% in the last 24 hours.

However, Bitcoin is far from the only player in the game, and there are numerous altcoins that have reached multi-billion dollar valuations. The second largest cryptocurrency is Ethereum, which supports smart contracts and allows users to make highly complex decentralized applications. In fact, Ethereum has grown so large that the word “altcoin” is rarely used to describe it now.
Tokens, on the other hand, are crypto assets that have been issued on top of other blockchain networks. The most popular platform for issuing tokens is Ethereum, and examples of Ethereum-based tokens are MKR, UNI and YFI. Even though you can freely transact with these tokens, you cannot use them to pay Ethereum transaction fees.
Cryptocurrencies such as Bitcoin feature an algorithm that adjusts the mining difficulty depending on how much computing power is being used to mine it. In other words – as more and more people and businesses start mining Bitcoin, mining Bitcoin becomes more difficult and resource-intensive. This feature is implemented so that the Bitcoin block time remains close to its 10 minute target and the supply of BTC follows a predictable curve.

Cryptocurrency market
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.
However, not all cryptocurrencies work in the same way. While all cryptocurrencies leverage cryptographic methods to some extent (hence the name), we can now find a number of different cryptocurrency designs that all have their own strengths and weaknesses.
Cryptocurrency exchanges provide markets where cryptocurrencies are bought and sold 24/7. Depending on the exchange, cryptocurrencies can be traded against other cryptocurrencies (for example BTC/ETH) or against fiat currencies like USD or EUR (for example BTC/USD). On exchanges, traders submit orders that specify either the highest price at which they’re willing to buy the cryptocurrency, or the lowest price at which they’re willing to sell. These market dynamics ultimately determine the current price of any given cryptocurrency.
