Jordan Kelley, founder of Robocoin, launched the first bitcoin ATM in the United States on 20 February 2014. The kiosk installed in Austin, Texas, is similar to bank ATMs but has scanners to read government-issued identification such as a driver’s license or a passport to confirm users’ identities https://taoxoan.info/.
There exist multiple methods of storing keys or seed in a wallet. These methods range from using paper wallets (which are public, private, or seed keys written on paper), to using hardware wallets (which are hardware to store your wallet information), to a digital wallet (which is a computer with software hosting your wallet information), to hosting your wallet using an exchange where cryptocurrency is traded, or by storing your wallet information on a digital medium such as plaintext.
The first cryptocurrency was bitcoin, which was first released as open-source software in 2009. As of June 2023, there were more than 25,000 other cryptocurrencies in the marketplace, of which more than 40 had a market capitalization exceeding $1 billion. As of April 2025, the cryptocurrency market capitalization was already estimated at $2.76 trillion.
The market capitalization of a cryptocurrency is calculated by multiplying the price by the number of coins in circulation. The total cryptocurrency market cap has historically been dominated by bitcoin accounting for at least 50% of the market cap value where altcoins have increased and decreased in market cap value in relation to bitcoin. Bitcoin’s value is largely determined by speculation among other technological limiting factors known as blockchain rewards coded into the architecture technology of bitcoin itself. The cryptocurrency market cap follows a trend known as the “halving”, which is when the block rewards received from bitcoin are halved due to technological mandated limited factors instilled into bitcoin which in turn limits the supply of bitcoin. As the date reaches near of a halving (twice thus far historically) the cryptocurrency market cap increases, followed by a downtrend.

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. 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.
Even though market cap is a widely used metric, it can sometimes be misleading. A good rule of thumb is that the usefulness of any given cryptocurrency’s market cap metric increases in proportion with the cryptocurrency’s trading volume. If a cryptocurrency is actively traded and has deep liquidity across many different exchanges, it becomes much harder for single actors to manipulate prices and create an unrealistic market cap for the cryptocurrency.
The two major categories of cryptocurrencies are Proof-of-Work and Proof-of-Stake. Proof-of-Work coins use mining, while Proof-of-Stake coins use staking to achieve consensus about the state of the ledger.
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.
